MilSpace2: Spectrum monitoring dual satellite system
Defence organisations are becoming increasingly dependent on space for its deployment. Consider, for example, the large number of satellites, which are important for communication, navigation and observation. The Dutch Ministry of Defence will want to develop more in the space domain in the coming years as well as address its dependence on it and the threats and developments in this area. This is described in the Dutch Defence Space Agenda.
Ahead of this, a successful Flight Readiness Review was completed on 28 November for the MilSpace 2 satellites. The MilSpace2 satellite system will demonstrate the military use of a microsatellite spectrum monitoring system and will build on the experience of the Norwegian NorSat-3 and the Dutch BRIK-II missions.
Almost ready for the launch Milspace 2 is a project that has been running for 5 years and has led, among other things, to the design and realisation of the two Milspace 2 satellites Birkeland and Huygens. The launch of the Milspace 2 satellites is scheduled for December this year.
This is the first time Norway and The Netherlands launch a constellation of satellites that will fly in tandem, which means the involved parties gain experience in formation flying throughout the project.
Working in tandem
The Milspace 2 mission will provide a non-cooperative and all-weather capability for detecting radars of interest. The two nano-satellites will both be able to measure the "Angle of Arrival" (AoA), and, when working in tandem, will offer improved geolocation accuracy thanks to the time of arrival difference (TDoA). This is the first known concept to offer combined AoA and TDoA for a two-satellite system.
Cooperation between the Netherlands and Norway
The Strategic Mutual Assistance in Research and Technology (SMART) Military Use of Space (MilSpace) Science & Technology cooperation is a bilateral agreement between the Ministry of Defence of the Kingdom of the Netherlands and the Ministry of Defence of the Kingdom of Norway. The project team, acting on behalf of the MoDs, consists of FFI from Norway and NLR and TNO from the Netherlands.

TNO’s view of 2030: Getting a grip on climate change from space
Greenhouse gas emissions in the atmosphere are one of the main contributors to climate change and must therefore be rapidly reduced if we are to meet the 2030 climate targets. TNO is working on new satellite technology that makes it possible to do so. Because the better we identify emissions, the more targeted the action we can take.
SmallCAT laser communication system delivered for integration to Norwegian NORSAT-TD Spacecraft
The SmallCAT uses new optical communication technology that uses satellites to send information to Earth. This happens via invisible light signals and enables much faster data transfers than using the radio frequencies currently employed for communication everywhere.
Consortium led by TNO successfully transmits data via laser communication between optical terminals over 10 km ground-to-ground link
Successful field test of 10 km optical laser communication link Laser satellite communication uses satellites that send information to earth in the form of invisible light signals.
Military use of space
TNO has made four recommendations to make us less vulnerable to satellite failure or misuse on a civilian and military level.
