Air Force Research Laboratory announces new space experiments

AFRL's Space Vehicles Directorate will study the physics of very low Earth orbit, and will pursue sensor technologies for cislunar space

WASHINGTON — The Air Force Research Laboratory announced Sept. 2 it will pursue two new space experiments — one will test the performance of satellite instruments in low orbits and the other is to advance sensor technology to monitor cislunar space

The experiments are run by AFRL's Space Vehicles Directorate at Kirtland Air Force Base, New Mexico.

Col. Eric Felt, the director of the Space Vehicles Directorate, said 27 teams submitted proposals and the two projects that won address important areas of space that impact national security.

The experiment known as “Precise” will study the physics of very low Earth orbit, or VLEO, which extends from 90 to 600 kilometers aboveEarth. AFRL said the experiment will examine the ionosphere and how gases impact radio propagation used for communications and navigation.

“The experiment will use sensitive satellite instruments and radio waves to examine changes in the ionosphere resulting from different compositions of ion source gases,” AFRL said in a statement.

Felt in June during a SpaceNews webinar mentioned that VLEO was an area of interest for AFRL. “This is like where you have to be thrusting all the time just to keep your satellite in orbit, at 200 to 300 kilometers,” Felt said.

The second project, named Cislunar Highway Patrol System. or CHPS, will focus on space domain awareness beyond geosynchronous Earth orbit (GEO) all the way out to the moon.

“CHPS will explore concepts for object detection and tracking between GEO, where most U.S. Space Force satellites are flown, and the moon,” said AFRL.

NASA and commercial companies seek to harvest resources and return to the moon, Capt David Buehler, AFRL program manager said. “This increase in activity will require greater domain awareness. We want to be there providing safety of flight when the U.S. puts boots back on the moon.”

The CHPS experiment will investigate sensing technologies and algorithms for object tracking.

“We need to address really basic things that start to break down beyond GEO, like how do we even write down a trajectory. The current space catalog uses Two-Line Elements, or TLEs, which simply do not capture the complex orbital dynamics and have almost no meaning in cislunar space,” said Jaime Stearns, principal investigator.

The next steps for the project leaders will be to submit budgets, program timelines and specific technical objectives by Oct. 1.

At the SpaceNews webinar, Felt said the “best payoff comes from pursuing things that we're not currently doing in space today.”

    German, Norwegian officials huddle over joint submarine program

    By: Sebastian Sprenger COLOGNE, Germany — Senior German and Norwegian defense officials met in Munich on Monday to plot a path for the two countries' multibillion-dollar joint submarine program. Officials said the meeting by the naval chiefs and defense-acquisition leaders was meant to push toward an agreement on the timing, cost and performance characteristics of the 212-CD program. The plan, these officials said, is to have the program on contract with lead vendor ThyssenKrupp Marine Systems in 2020, with the first vessel delivered to Norway in late 2026. A deal with the German shipyard was previously envisioned for this year. The design of the new boats has yet to be locked down, which may reflect a last glimmer of hope in Berlin and Oslo that other countries in the market for submarines — namely Italy, the Netherlands or Poland — could join the effort. Germany and Norway inked a strategic cooperation agreement on submarines in 2017. The idea is for TKMS to produce six identical boats — two for Germany and four for Norway. Norwegian missile-maker Kongsberg, in turn, will outfit German Navy ships with an upgraded variant of its Naval Strike Missile. The stakes are high for the program, as any delays in fielding the submarines would throw off military plans in either country. The German Navy has seen years of delays in its F-125 frigate program. According to the service, an industry consortium led by TKMS is to blame. The German military, which is seeking a budget boost beyond what is on the books so far, is under pressure to field equipment on time and on budget. The idea is to prove that the defense-acquisition apparatus can convert additional money into additional capability. As a result, officials are increasingly tight-lipped about details surrounding big-ticket projects beyond rosy statements. “After a successful meeting: We are convinced that we want to make #U212CD a success story,” German Navy chief Vice Adm. Andreas Krause wrote on Twitter late Monday. “We will act and speak as if we were ONE Navy. Both navies need the new submarines delivered in time, cost and quality. Everyone involved in this project should never forget its relevance.” Sebastian Bruns, a naval analyst with the University of Kiel in northern Germany, said the interplay between the German and Norwegian defense bureaucracies will be crucial as the program progresses. “This type of integrated process is new for Germany,” Bruns told Defense News. That is because everything from spare parts to training and operational aspects is designed to be bilateral from the start, possibly tying the two sea services together for decades. “We are talking about a time frame through the 2060s,” he said. Bruns added that questions remain about Germany's future defense budget and whether the submarine program will have to compete with other national priorities. According to a Navy spokesman, the program is reflected in the Defence Ministry's broad budget outlines. Lawmakers are expected to get details for debate next year. https://www.defensenews.com/global/europe/2019/04/30/german-norwegian-officials-huddle-over-joint-submarine-program/

    Saab Selected as Combat System Provider for Finnish Squadron 2020 Programme

    September 19, 2019 - In accordance with Finland's Ministry of Defence's proposition, the Government of Finland has today selected Saab as the combat system provider and integrator for the Finnish Navy's four new Pohjanmaa-class corvettes within the Squadron 2020 programme. Saab has not yet signed a contract or received an order relating to Squadron 2020. Finland's Ministry of Defence has stated that the contract is scheduled to be signed on 26 September 2019 and that the order value will be 412 million Euro. “This announcement marks a major milestone in Saab's relationship with Finland and we look forward to continuing to support the Finnish Navy's capabilities with our world-leading combat system expertise”, says Anders Carp, Senior Vice President and head of Saab business area Surveillance. The contract period will be 2019-2027 and the scope will include a range of solutions, including Saab's 9LV Combat Management System, related sensors and other systems. All of the Finnish Navy's current vessels feature at least one system from Saab, with the majority of vessels operating several systems from Saab.
