Motorcycle taxi rider found buried in Gen. Mariano Alvarez, Cavite construction site
The body of a 31-year-old motorcycle taxi rider was found buried in a construction site in General Mariano Alvarez, Cavite, with authorities looking at jealousy as the motive for the killing as the victim was last seen with a man who fathered a child with his live-in partner. The victim, identified as Jayjay Caluza, was last seen early morning on June 24 riding along Trece Martires on the way to Dasmariñas, with a man riding pillion. The passenger, now considered to be a person of interest, was the former partner of Caluza's live-in partner, identified as Grace. The victim was missing for two weeks and was found buried in a construction site where the suspect was said to be the foreman. It was the last location in the global positioning system (GPS) of Caluza's motorcycle. Upon inspecting the area, authorities said they were suspicious of the workers as they all ran away when they were seen. The operating system of the backhoe also showed that it was used hours before the regular working hours, prompting authorities to ask the construction company to dig up the area. That was where Caluza's body was found. Three days before Caluza went missing, the suspect was said to have taken Grace, and forced her to stay with him and their child. He then asked Caluza to bring him to work, and that was the last time the victim was seen alive. 'Binantaan niya po si Jayjay na ano, papatayin kung hindi daw po ako sumama, kaya sumama na po ako,' Grace said in a report by Jonathan Andal on GMA's '24 Oras Weekend' on Sunday. 'Wala po akong pagmamahal doon sa lalaking 'yun eh. 'Yung sustento lang po niyang pera 'yung inaano ko kasi may anak din po kami non,' she added. (He threatened Jayjay that he would kill him if I did not come along, which is why I went… I have no love for that man. I was just after his financial sustenance because we have a child together.) Grace said she was also sure that there were multiple people involved in the killing of Caluza, as her former partner already detailed what they would do earlier. 'Hindi lang po isa ang gumawa noon. Tiyak po ako kasama 'yung mga pinsan niya dun eh. Nasabi na niya po 'yun eh, na aanuhin niya eh, baka pagtulungan nila 'yun si Jayjay eh, 'pag hindi ko pa daw nilayuan 'yun eh. Sobrang sakit ng ginawa niya sa taong 'yun. Nagtiwala 'yun eh,' she said. (More than one person did it. I am sure that his cousins were involved. He already said it before, that they would gang up on Jayjay if I didn't leave him. What they did to him was really painful. He trusted him.) According to Caluza's mother, Carmelita Caluza, her son suffered 12 stab wounds, based on a report from the Scene of the Crime Operatives (SOCO). 'Noon pong inano ng SOCO, labingdalawa daw po ang saksak niya eh, apat daw po dito sa may baga, tapos walo daw po sa likod. Talagang parang ginawa nilang hayop ang anak ko,' she said in the same report. 'Napakasakit ng ginawa mo. 'Yung anak ko sobrang bait. Napakabait ng anak ko na 'yan. Bakit mo ginawa? Bakit ginawa sa anak ko 'to? Bakit?' she added. (According to SOCO, he had 12 stab wounds. Four near the lungs, and eight in the back. What you did was very painful. My child was really kind. That son of mine was really kind. Why did you do it? Why did you do it to my child? Why?) For its part, Naic Police deputy chief of police Police Captain Grenie Dolnagon said they are looking at more than one person of interest. 'More than two and nakikita namin na person of interest. Actually marami po kaming nakausap diyan, 'yun nga lang iisa ang sinasabi—na hindi nila kilala, hindi nila alam, isang linggo lang sila na nakatira doon,' he said. (We are looking at more than two persons of interest. Actually, we talked to a lot and they all say the same thing—they don't know them, they don't know, they have lived in the area for a week only.) The victim's family is now appealing for financial help to fund the funeral and the burial. 'Sana po mahanap na siya at kung sino man po ang kasama niya. Gusto ko pong mabigyan ng hustisya 'yung anak kong namatay,' the victim's mother Carmelita said. (Hopefully he, and whoever else was involved, is found. I want justice for my child who died.) — Jon Viktor D. Cabuenas/BM, GMA Integrated News

Jamming and spoofing: The threat airlines deal with every day
The manipulation occurs for planes as flights pass adjacent to areas where militaries disrupt or alter GPS signals to ward off attacks, confuse hostile drones and missiles, or harass pilots. Civilian airlines flying long-haul routes, such as those between Australia and Europe, can be affected. GPS jamming, conducted by military forces, is near constant around Ukraine and parts of Russia. At any given time, the incidence of spoofing that affects commercial airspace shifts. But to give an example, in July to August 2024, the top airspace regions affected by spoofing were Cyprus, Israel, Egypt, Turkey, Russia and Pakistan, according to GPS Spoofing Workgroup report. There has been a more than 200 per cent increase in Global Positioning System loss events between 2021 and 2024, according to the International Air Transport Association (IATA). 'With continued geopolitical tensions, it is difficult to see this trend reversing in the near term,' said Nick Careen, IATA's senior vice president for operations, safety and security. Spoofing can create some strange effects in the cockpit, like being at 30,000 feet when an alarm comes on telling the pilot to immediately pull up to avoid the ground, or the clocks used by the captain and first officer no longer read the same time. An instrument can falsely indicate a plane is far from its actual location. Another pilot, who flies through affected regions, said GPS jamming now happens daily. The aircraft loses the connection to the GPS, and it flies a bit further and regains the signal again. 'It's no big deal if it's for a limited time while en route.' GPS spoofing, while less frequent, poses a bigger problem, the pilot said. 'That is much more serious if it goes haywire.' It can change the timing of clocks in the aircraft and in the worst case, it can mess with the instruments reading the position of the plane, he said. Planes with their GPS spoofed can unexpectedly turn without air traffic control clearance, deviating from their cleared route. This can put them at risk of entering dangerous or military areas, as almost occurred in 2023 on a flight from Europe to Dubai, according to OpsGroup, an organisation of international flight operations professionals. There's some history here. Civilian planes didn't use GPS until after Korean Air Lines flight 007 was shot down by Soviet aircraft in 1983 after it drifted into Russian airspace. The downing of the Boeing 747-230B, amid Cold War tensions, killed 269 people, and prompted the US government to permit the US-built GPS system to be used for civilian aviation. Experts fear that the abundance of false alarms around GPS can erode a pilot's awareness, or increase distrust of the data. A recent OpsGroup report identified loss of safe distance between other planes on the air route due to false instruments warnings as one of the safety concern arising from spoofing. The GPS Spoofing WorkGroup report also cited instances of surprise altitude climbs by planes initiated by the ground avoidance system in the cockpit. Loading There is also a longer-term effect, too. 'Due to now commonplace encounters of GPS spoofing impacts, there is a gradual, insidious acceptance of increasingly higher risk at [an] organisational level,' a 2024 report concluded. 'Small changes and new behaviours that were slight deviations from the normal course of events gradually become the norm, providing a basis for accepting additional deviance and, typically, higher risk.' A phenomenon known as 'spoofing fatigue' is also emerging: pilots accustomed to frequent spoofing incidents simply stop reporting them. This can lead to a normalising of risk and reduced situational awareness. Different readings on instruments in the cockpit can also cause disagreements between pilots and other crew members regarding the best course of action, clouding the decision-making needed for a safe flight. The pilot interviewed by this masthead said that when they lose GPS en route: 'We basically don't do anything unless a secondary navigation system warns that the plane's route is becoming less precise.' Planes can activate a back-up system called Distance Measuring Equipment, which had been the standard before GPS became commonplace. The pilot said he has never been lost because of jamming or spoofing; however he has been 'slightly off track' and had to ask air traffic control for help. 'That has been because of prolonged GPS loss.' In the pilot's region and with his company, the GPS interference phenomenon is well understood. 'So we have a spoofing guide/checklist so we can prevent some follow-on effects' There can be complex situations but he said, 'We always have back-up plans.' While pilots adapt, lack of GPS can have serious consequences. On Christmas Day last year, Azerbaijan Airlines Flight 8243 left Baku for Grozy in the Russian republic of Chechnya when it lost its GPS signal. Russian military forces in Grozny, on guard for Ukrainian drone attacks, had been GPS jamming the area. Flight 8243 tried to approach Grozny twice, said FrontierSI's technical lead Eldar Rubinov. The plane lost GPS on approach to Grozny and asked air traffic controllers for guidance to the runway, he said. Loading 'They tried the approach twice, but both times when they reached the decision-making height (or minimum), they were still above the clouds and couldn't establish a visual contact with the runway.' 'After the second attempt, they indicated to the air traffic control, that they cannot land and they are returning to Baku, and that's when they got shot by an anti-aircraft missile.' The pilots mistook the sound of the missile hit for birdstrike. The plane crashed, killing 38 people while 29 survived with injuries. 'If they had GPS, their minimum would be much lower, so they could've descended below the clouds without any issues,' said Rubinov, who audited the plane's blackbox recording. The lack of GPS was a contributing factor to the crash, Rubinov said. In response to the growing problem of GPS interference, IATA along with the European Union Aviation Safety Agency last month proposed several solutions: standardising radio calls for GPS interference, establishing monitoring and warning practices, and facilitating information sharing. The groups also advocate for restrictions on jamming devices, though the effectiveness of such restrictions is questionable in regions like Russia's Kaliningrad, a major jamming hotspot, or in Israel. Another potential solution for commercial flights is a controlled reception pattern antenna (CRPA). This technology can detect and completely block interfering signals from a specific direction, making it almost unjammable.

Daniel Kleppner, Physicist Who Brought Precision to GPS, Dies at 92
Daniel Kleppner, an experimental physicist who helped to develop an atomic clock that became an essential part of global positioning systems, or GPS, and who also helped to discover a rare fundamental state of matter predicted by Albert Einstein and his fellow theoretical physicist Satyendra Nath Bose, died on June 16 in Palo Alto, Calif. He was 92. His wife, Beatrice, confirmed the death. She said he collapsed while visiting their daughter, Sofie Kleppner, and her son, Darwin, who was graduating from high school. It was in the mid-1950s, while he was doing a fellowship at the University of Cambridge in England, that Dr. Kleppner learned something surprising: It was possible, a tutor told him, to build a clock precise enough to detect the effects of gravity on time. Curious, he went in search of more information and read Norman Ramsey's 1953 book 'Nuclear Moments.' After his fellowship, he went on to do graduate work at Harvard University, where he discovered that Dr. Ramsey was on the faculty. He immediately applied for Dr. Ramsey's research group and was accepted. Dr. Ramsey would eventually share the 1989 Nobel Prize in Physics for research he had done in the 1940s, when he discovered a way to measure the frequencies of electromagnetic radiation absorbed by atoms and molecules. His experimental technique laid the groundwork for nuclear magnetic resonance, a precursor to the M.R.I. technology used in medicine today. The atoms of each element vibrate at a unique frequency, like the signature call of a bird. Dr. Ramsey's work made it possible for scientists to build what is known as an atomic clock — a device that measures those vibrations, using the information to keep incredibly precise time. (The official measure of a second, for example, is 9,192,631,770 oscillations of a cesium atom.) Want all of The Times? Subscribe.

Govt MPs to attend retreat next week
Deputy prime minister Fadillah Yusof said he can help to brief government MPs from Sarawak and Sabah. PETALING JAYA : The unity government will hold a retreat for all government MPs next week, says deputy prime minister Fadillah Yusof. Fadillah said the retreat will allow the MPs to have a better understanding of the national issues that Putrajaya is facing, Bernama reported. Responding to questions about whether Gabungan Parti Sarawak MPs were present during a meeting between Prime Minister Anwar Ibrahim and Barisan Nasional MPs in Putrajaya last night, Fadillah said he is willing to brief MPs from GPS and Gabungan Rakyat Sabah if required. 'For GPS, we have no issue. With our small number of MPs, I can engage with them directly. These matters were discussed in the Cabinet, so I know what needs to be clarified. 'The prime minister would have limited time if he were to meet all MPs individually. I can assist by briefing GPS and GRS MPs. 'A retreat involving all unity government MPs, including ministers and deputy ministers, is scheduled for next week. We'll use that platform to provide further explanations,' Fadillah, a senior vice-president of GPS lynchpin Parti Pesaka Bumiputera Bersatu, told reporters in Kuching today. Anwar attended a unity government retreat with 27 ministers at the Seri Perdana Complex in Putrajaya in January 2023. Bernama reported that the retreat was made up of briefing sessions covering key issues such as the implementation of key performance indicators, government structures, public administration affairs, and financial management. The sessions also touched on government procurement, government protocol, professionalism, sustainable development, economic scenarios and media communication. Earlier today, BN secretary-general Zambry Abdul Kadir said BN MPs met with Anwar at his official residence in Putrajaya last night as part of regular engagements with all parties in the unity government. He said the meeting revolved around policies and current matters that required clarification from the prime minister. Pakatan Harapan MPs and senators have been invited to a meeting with Anwar at his official residence in Putrajaya on July 14.
