El final del GPS

El GPS es en un actor económico y militar fundamental. North Corea ha interferido  el sistema GPS de Corea del Sur. Los satélites y el control de tierra son sometidos a ataques de tipo cibernético. Hay equipos (el ruso  R-330ZH Zhitel) para producir interferencias. El programa GPS OCX está para renovar la infraestructura del control terrestre. Raytheon está encargada para su desarrollo. OCX está retrasado al menos 2 años al igual que los nuevos satélites GPS III que usarán el software OCX.  Mayflower ha sido designada para el  programa MGUE, sobre un módulo receptor  de avanzadas prestaciones militares. Para 2020 habrá un nuevo GPS.

GPS was first developed in the 1960s to allow ships in the U.S. Navy to navigate oceans more accurately. The first system included five satellites that allowed ships to check their location once every hour. Today’s system includes more than two dozen satellites, allowing nearly instantaneous precision location to within a few meters. The applications, across industries, are endless.

Since 1983, GPS has been available to anyone with a GPS receiver. Airlines, shipping companies, trucking firms, farmers, bankers and drivers everywhere reap the benefits of the world’s greatest free utility on a daily basis. Click on each of the icons above to learn more.

GPS MODERNIZATION

The current GPS system consists of two key segments: space and ground control. The space segment includes the constellation of multiple satellites currently on orbit, while the control segment consists of the ground-based stations that are responsible for tracking, monitoring, and updating of the satellites. As part of an historic modernization effort, Raytheon will deliver the full enhanced ground control segment, commonly referred to as GPS operational control system or GPS OCX in 2021.

GPS OCX

Together with next-generation satellites, GPS OCX will provide improved accuracy of the current system and will be able to fly more than twice as many satellites. Those additional satellites will increase coverage in hard-to-reach areas such as urban canyons and mountainous terrain.

GPS OCX will be the first major defense program to be fully secure and protected from hacking, interruption or signal and information compromise. The cyber-secure system will have improved accuracy with better international availability as well as globally deployed modernized receivers with anti-jam capabilities.

IMPORTANT MILESTONES

Deliverables for the entire GPS OCX system are divided into three blocks: Block 0, Block 1 and Block 2. Block 0 delivery took place in the fall of 2017, enabling it to support the first launch of modernized GPS III satellites in 2018. Block 1 delivery will take place in 2021, providing full operational capability to include control of both legacy and modernized satellites and signals. Block 2, delivered concurrently with Block 1, adds operational control of the new international L1C and modernized Military Code signals.
