U.S. Army Pursues Alternatives To GPS

Jen DiMascio

In its attempt to ensure that soldiers have access to GPS-like information, even when access to those U.S. Air Force satellites may be compromised, the U.S. Army is in the process of fielding an alternative system on certain ground vehicles.

The Army began fielding the first iteration of the Mounted Assured Positioning, Navigation and Timing System (MAPS), an anti-jam GPS alternative, on General Dynamics Stryker vehicles in the 2nd Cavalry Regiment this year. The service will field 300 such systems to the 2nd Cav this year, according to Willie Nelson, director of the Army's Assured Positioning, Navigation and Timing Cross Functional Team. Thousands are supposed to be installed into vehicles in U.S. European Command by 2028.

On Oct. 15, the U.S. Army announced it had chosen Collins Aerospace to provide a next-generation MAPS for manned ground vehicles. Collins will make MAPS Gen II, systems that will be evaluated for a year and potentially be fielded to 8,000 additional vehicles. The Collins Aerospace system combines the NavHub-100 navigation system and Digital GPS Anti-jam Receiver-100. The system adds a military code capability and modernized signal tracking to improve reliability and integrity, Collins says.

The MAPS program is part of the U.S. Army's focus on modernization. But it is also a response to a request from commanders in Europe and Korea, according to Gen. John Murray, commander of Army Futures Command. The Army maintains that its effort to look for alternate means of positioning, navigation and timing is aligned with the U.S. Air Force's plans for GPS satellites.

Asked about the threat from Russia, Brig Gen. Robert Collins, program executive officer for intelligence, electronic warfare and sensors, said the U.S. needs confidence not just in the ability of U.S. assets to withstand jamming attacks but to be able to fend off spoofing efforts as well.

“The electromagnetic spectrum is becoming contested and people are operating in that space,” Collins said. “We recognize that our traditional GPS today is not where we need it to be from a survivability perspective. So we have looked at how to make it more hardened.”

Along with those efforts, the Army has also planned an industry day for Oct. 29-31, as it seeks new inertial measurement unit and timing technologies.

    Will the Thai Air Force get more Gripen jets?

    By: Valerie Insinna SURAT THANI AIR FORCE BASE, Thailand — The Royal Thai Air Force's Wing 7, home to all of the country's Saab Gripen aircraft, wants more jets. The question is whether the country's defense budget will allow for it, one official said Tuesday. “As operators, we know that this is a very good aircraft, and we would love to have more,” said Group Capt. Prachya Tippayarat, deputy commander of the RTAF's Wing 7. “But it's just that I don't know when. The Air Force will have to think about that.” The RTAF currently operates 11 Gripen C/D fighter jets, bought from the Swedish government and manufactured by Saab. The Air Force lost one Gripen in a 2017 crash that destroyed the jet and killed the pilot. With 11 jets left, it is more difficult to accomplish both training and maintenance, Tippayarat said. “So of course we are looking for the replacement for the 12th one. It's just a matter of when. As the operator, we cannot tell when we are going to have that aircraft,” he said, adding that the service might have other budget priorities. Thailand's 11 Gripen aircraft are operated from Surat Thani Air Force Base, located about 328 miles south of Bangkok. Defense News visited the base Nov. 27-28 and accepted airfare and accommodations from Saab. Surat Thani plays a key role in defending southern Thailand. Although the nation also operates Northrop Grumman F-5s and Lockheed Martin F-16s, Wing 7's Gripens are the Royal Thai Air Force's premier fighters, used primarily for air-to-air and air-to-ground combat, and for secondary missions such as reconnaissance, Tippayarat said. The Thai government is also considering an upgrade of the RTAF Gripens' software suite, he added. The jets are currently configured to the MS19 standard, but the potential upgrade to MS20 would bring the jets into the most advanced configuration for the Gripen C/D. The MS20 software adds capabilities that make the Gripen a more formidable jet for air-to-ground attacks, including an electro-optical pod that allows the jet to drop laser-guided weapons, the addition of Boeing's Small Diameter Bomb and MBDA's Meteor missile, and new radar modes. One MS20 enhancement that the RTAF won't need is the addition of Link 16 capability, the data link used by NATO and its partner nations. The RTAF Gripens run on the Thai military's indigenous network, Link T. If Link 16 functionality is needed, the service can use its F-16s, but operating Link T on the Gripen allows Thailand to protect its homegrown capabilities and information, Tippayarat said. Saab delivered the first Gripens to Thailand in 2011. Other Gripen C/D users include Sweden, Hungary, the Czech Republic and South Africa. https://www.defensenews.com/global/asia-pacific/2018/11/28/will-the-thai-air-force-get-more-gripens

    German army relies on Rohde And Schwarz

    Munich 22-Jul-2019 - IDZ-ES and the PUMA infantry fighting vehicle (IFV) for the VJTF 2023 are making a start on the end-to-end digital command radio link over the first mile using software defined radios from Rohde & Schwarz. The seamless command radio link for the PUMA armored infantry system with the infantryman of the future (IdZ-ES) for the Very High Readiness Joint Taskforce (VJTF) 2023 is provided by Rohde & Schwarz. With the Budget Committee of the German Lower House of German Parliament (Bundestag) having given its approval for the armored infantry system service package at the end of June, the necessary contracts for procurement have now also been completed. "This order is a milestone that we have reached after winning against international competitors in challenging trials and comparative tests set by the German Armed Forces (Bundeswehr) in 2018 in Munster, Germany," explained Hartmut Jäschke, Senior Vice President Market Segments Secure Communications Sales and Projects at Rohde & Schwarz. Its basis is the intention of the Bundeswehr to be ready with the PUMA IFV/armored infantry system and the latest version of IdZ-ES for NATO VJTF (Land) in 2023. Rohde & Schwarz is a subcontractor of Rheinmetall Electronics, which is responsible for the IdZ-ES system, and will supply the latest tactical software defined radios (SDR) together with suitable waveforms, integration, training and services. The SOVERON family works with the high data rate and interference-immune SOVERON WAVE waveforms for tactical rugged use on the first mile, and is thus an exact match for the spectrum of requirements of a battle group for territorial and collective defense as well as for international crisis management operations. All members of the SOVERON WAVE family of waveforms offer mobile ad hoc network (MANET) functionality. Radios equipped with this capability function as routers within the IP network group, forwarding the information via other communication nodes and thus ensuring that a robust, interference-immune link can be maintained under all circumstances. The Rohde & Schwarz VHF/UHF radio systems selected for this project will establish and maintain the command radio link with simultaneous voice and IP data from dismounted troops up to the platoon and company level. The systems concerned are handheld (SDHR/SOVERON HR) and vehicular radios (SDTR/SOVERON VR) that are interoperable with the German Armed Forces joint radio system (SVFuA, series name: SOVERON D) that has already been commissioned by the Bundeswehr and the SDR waveforms procured with it. The first batch of SOVERON D commissioned for command vehicles will be delivered to the troops in the first half of 2020. This interplay is also of great importance for future viability in the context of the Digitalization of Land Based Operations/Tactical Edge Networking (D-LBO/TEN) major project for highly secure and trusted interoperable connections that will only come into effect after VJTF 2023. SOVERON D also provides backward compatibility with the analog SEM radio infrastructure that will be in service for some time yet even though it is obsolete. This capability was also recently demonstrated in further tests. "With our innovative overall approach – SOVERON – we provide national trusted solutions that can be tailored to the customer's needs but which, due to their open architecture, are compatible with established radio systems and architectures and, at the same time, will be viable in the future," Mr. Jäschke continued. "It is an honor for us to bring into operation by the troops the latest state of the art for the VJTF. By doing so, we are not only paving the way for the next steps of D-LBO/TEN and for further strategic projects of the Bundeswehr. There are also significant synergies with the Telecommunications of the Army (TK A) project in Switzerland, comparable to the networking part of D-LBO/TEN. We are in the final round of a multi-year competition here."
