    GPS ground stations that are contracted by Raytheon Technologies to replace the current ground stations are more than seven years behind schedule and lawmakers are not happy, reported Defense One. This delay has caused the U.S. Department of Defense (DOD) to go over its yearly budget and has sparked discussions as to future budget allocations for the U.S. Space Force (USSF) to continue to control and enhance the GPS constellation.

    The USSF has been working to replace the current GPS ground stations with the GPS Next Generation Operational Control Segment (OCX) program since 2016. The operation was first delayed when the COVID-19 pandemic swept the world.

    The additional delay was caused by efforts to replace IBM as the OCX hardware supplier after IBM sold its server product line to the Chinese company, Lenovo. The Pentagon believed the OCX program would be at a high risk for Chinese hacking after the sale to Lenovo, and in response, the contract with Raytheon was modified to replace the hardware with HP in 2020.

    All of the delays have come at a cost, as the replacement of ground control stations has increased from $4 billion to $7 billion — a 73% increase over the original estimate — which was reported by a Government Accountability Office report in June.

    Lawmakers wrote in the 2024 DOD appropriations bill, “[t]he fiscal year 2024 President’s budget request for the Space Force is $30,197,634,000, an increase of $3,907,806,000 or 15[%] over last year’s enacted level, continuing a trend of double digit growth over the past several years… [h]owever, despite these significant increases, the budget request continues to include serious shortfalls and disconnects.”

    The USSF operates 32 GPS satellites, including six of the expected 10 next-generation GPS III satellites. However, some of the new satellites’ capabilities, including increased jamming resistance, can only be used once OCX comes online.

    The lawmakers shared their displeasure with the OCX program delay, “[t]his is unacceptable and demands senior leader attention to ensure the program has the appropriate resources to complete OCX development and deliver the capability as soon as possible. The Committee remains concerned by other poor performing programs including Space Command and Control, Family of Advanced Beyond-line-of-site Terminals, Military GPS User Equipment Increment 1, and Enterprise Ground Services.”

  • Turkish satnav station opens in Antarctica

    Turkish satnav station opens in Antarctica

    Turkey has opened GNSS base station in Antarctica, according to Sputnik News. The station can track changes in the location of icebergs and transmit photos of Antarctica’s surface, as well as process data from GPS, GLONASS and Galileo.

    “A GNSS satellite navigation base station was set up within the framework of the fourth Turkish scientific expedition to Antarctica,” said Turkish Industry and Technology Minister Mustafa Varank, as quoted by the national Anadolu news agency. “A group of specialists from the Turkish General Directorate of Mapping has built Turkey’s first GNSS base station abroad.”

    The Fourth Antarctic Expedition of Turkey began on Feb. 9 under the coordination of the Scientific and Technological Research Council (TUBITAK) Polar Research Institute. The GNSS station operates on Dismal Island, 73 kilometres (45 miles) from Horseshoe Island, where the temporary Turkish science base is located.

    The 24-member Turkish research team joins 15 scientific projects in the Earth, life, and marine sciences. The expedition is being conducted under the auspices of the Turkish Presidential Administration and the Ministry of Industry and Technology and coordinated by the TUBITAK.
