The U.S. Air Force is getting ready to deliver the first of its next-generation GPS III satellites into orbit later this year, and expects the new satellites to deliver significant capability improvements. But much work also needs to be done on Earth to make sure the Air Force is able to get the most out of the platforms.
That's why Lockheed Martin will begin a series of updates to the architecture's ground control system following the initial launch, according to a statement from the company. These updates will give the Air Force get a head start on testing and operations before the majority of the constellation is in place.
The Air Force placed Lockheed Martin on contract in 2016 and 2017 to upgrade the existing Architecture Evolution Plan (AEP) Operational Control System (OCS) called GPS III Contingency Operations (COps) and M-Code Early Use (MCEU), respectively. Just as the GPS III satellites themselves are equipped with improved anti-jamming technology and more accurate signals transmission capability, the ground systems and software that control them need to be upgraded as well.
The Air Force has also worked with Raytheon on the estimated $6 billion Operational Control Segment program, often referred to as OCX. That program is expected to serve as the primary ground control system for the GPS III program but has been behind schedule. SpaceNews recently reported the target completion date for Block 1 of the program is June 2021. Block O, the launch and checkout system, was delivered in September 2017.
ockheed Martin's contingency program will allow the existing control system to support and integrate more powerful GPS III satellites. Modifications will support GPS III satellites in their position, navigation and timing missions, coordinating their movement with GPS IIR, IIR-M and IIF satellites already in orbit.
A second set of upgrades, known as the MCEU modernization program, will focus on the development of M-Code, a new advanced signal designed to improve anti-jamming and anti-spoofing capabilities. The program will improve the existing ground system and allow it to task, upload and monitor M-Code within the GPS constellation. In other words, MCEU modernization will help the Air Force integrate and test GPS III satellites into the current constellation earlier.
COps is on schedule for delivery in May 2019 and MCEU is scheduled for delivery in January 2020.

The push can be expected to have an influential impact on Sweden's own decision-making process regarding NATO membership.

MBDA a procédé à la première démonstration des capacités opérationnelles de LYNKEUS Dismounted, comprenant le système MMP (Missile Moyenne Portée), en liaison radio avec le drone Novadem NX70. « Le drone a permis la détection et l'identification d'un char situé hors du champ de vision de l'opérateur. Les coordonnées de la cible ont ensuite été transférées au poste de tir MMP, selon une séquence illustrant la possibilité d'engager une cible qui n'a jamais été en vue directe du tireur », détaille MBDA. La démonstration s'est conclue par un impact direct sur la cible. Le succès de ce premier tir « vient confirmer les capacités offertes par LYNKEUS de maîtrise et de qualité de la chaîne d'informations allant du drone au poste de tir, et prouve également la précision de l'extraction des coordonnées de la cible », souligne MBDA.

by Pat Host General Atomics Aeronautical Systems Inc (GA-ASI) in March and April 2020 demonstrated three expanded automatic take-off and landing capability (ATLC) enhancements for its MQ-9A Reaper medium-altitude, long-endurance (MALE) unmanned aerial vehicle (UAV). One improvement enables the aircraft to land at an alternate, or divert, airfield in which no ground control station (GCS) is present while also under satellite communication (satcom) control, GA-ASI announced on 25 June. With the divert landing enhancement, the remote pilot can enter the new landing area co-ordinates to automatically land at the selected location. The pilot can also overfly and self-survey the divert airfield's runway using the Reaper's multispectral electro-optical/infrared (EO/IR) sensor to obtain co-ordinates for an automatic landing. Once uploaded to the MQ-9A's mission profile, the Reaper's aircrew enables the ATLC system, which allows the aircraft to automatically manoeuvre itself into a landing pattern and make the automatic landing. This enhancement will enable operational Reapers to land at alternate airfields on their own because of poor weather, changing mission requirements, or damaged runways, GA-ASI president David Alexander said in a 25 June statement. GA-ASI demonstrated this aerial runway survey capability on 23-24 April at GA-ASI's Gray Butte flight operations facility near Palmdale, California, a company spokesman said on 29 June. The second enhancement expands the cross-wind limits of the MQ-9A. The third improvement increases the maximum landing weight for normal and emergency landings. The heavyweight landings were demonstrated throughout March and April at the Southern California Logistics Airfield in Victorville, California. https://www.janes.com/defence-news/news-detail/general-atomics-develops-mq-9-reaper-automatic-take-off-and-landing-enhancements
