A spy satellite revolution?
Small, lower cost satellites are beginning to gain traction among intelligence agencies, says a top industry executive.
National security agencies are steadily testing out more small satellites before committing to new constellations of the lower-cost alternatives, according to Bill Gattle, the president of Space and Intelligence Systems at the Harris Corporation.
“We're seeing a lot more acceleration, certainly in the intelligence community, on their willingness to adopt it. We've certainly seen some things out of Army,” said Gattle, a former program director of terrestrial communications and director of engineering for defense programs at the Pentagon. “It's moved from ... customers being intrigued to believing it's worthy of a demo.”
Small satellites are typically no bigger than a refrigerator and weigh less than 180 kilograms, according to a NASA fact sheet. By comparison, some of the largest satellites are the size of a school bus. The reduced size means small satellites are typically cheaper but less capable than their larger counterparts. To make up for that gap, small sats can be launched in a constellation of tens or even hundreds of satellites, networked together, making the entire system more resilient if one goes offline.
At the beginning of 2018, Harris had three customers for its small sats. A year later, it has five government customers under contract for 17 small satellites. One of those is for an Army communications satellite, Gattle said, though the company could not provide additional details.
That doesn't mean there's been universal acceptance. Even Gattle acknowledges there are hurdles the small satellite industry needs to overcome to see sustained growth in the military and intelligence market.
“How do you get the data quickly from the satellite to the war fighter who needs it?” Gattle said. “It doesn't help you to know a missile landed five minutes ago. You have to have the timeline be very quick and you need need a communications backbone ... which will be pivotal to how fast this grows.”
Gattle also talked about the launch of Harris' first small satellite last month, how the company is going on a hiring spree and what 2019 has in store for the industry.

IAI ELTA Awarded 125 Million-Dollar Contract for Czech Mobile Air Defence Radar (MADR) Program
December 5, 2019 - ELTA Systems, a subsidiary of Israel Aerospace Industries (IAI), announced that a Government-to-Government (GTG), contract has been signed today in Prague, by the International Defense Cooperation Directorate (SIBAT), at the Israel Ministry of Defense and the Czech Ministry of Defense. The agreement was signed for the Czech Mobile Air Defense Radar (MADR), program and comprises eight ELTA ELM-2084 Multi-Mission Radars (MMR) with air surveillance, air defense, and artillery capabilities. IAI's ELTA will assume the role of prime contractor. The MADR systems will be delivered, tested, licensed and accepted in operational condition during 2021-2023 in the Czech Republic, and will be adapted to operate in accordance with Czech and NATO command and control systems. The Israeli party will transfer state-of-the-art technology and know-how. The program also includes a substantial contribution from Czech industries, amounting to 30% of the contract value. The cooperation with local companies will apply to all parts of the program including design, manufacturing, assembly, integration, testing and life-time maintenance of the systems. Certain security components will be manufactured locally, including advanced Gallium Nitride (GaN) radar modules, as well as auxiliary sub-systems such as trucks and camouflage nets. This agreement is part of the ongoing and excellent cooperation between the two countries on the political, industrial, defense and homeland security levels. Yoav Tourgeman, IAI VP and CEO of ELTA, stated “The MADR program expands the global use of the ELM- 2084 MMR radar, known as the "Iron Dome" system radar, which currently includes over 100 systems contracted worldwide (including NATO countries). We are proud and honored to supply the best combat proven multi-mission radar to the Czech armed forces. These radars will propel forward the Czech Air-force capabilities and enable to confront the most advanced aerial threats. We believe that MADR program pave the path to additional cooperation between the Israeli and Czech defense industries. Director of SIBAT, Brig. Gen. (Ret.), Yair Kulas: “I applaud the agreement that was signed today with the Czech Ministry of Defense. Today is monumental for the State of Israel due to the history of the Czech support for the State of Israel, since its establishment 70 years ago. This agreement will deepen and strengthen the cooperation and relations with our Czech partners. It is an expression of confidence in the capabilities of the Israeli defense establishment and defense industries and highlights the significance of Israeli technology in the face of the threats shared by the international community. We hope to see this agreement opening the door for further cooperation with our Czech partners and with additional NATO states.” View source version on IAI : https://www.iai.co.il/iai-elta-awarded-125-million-dollar-contract-czech-mobile-air-defence-radar-madr-program
