Continuous connectivity to low earth orbiting satellites enables a new level of satellite efficiency and commercial possibility
Inmarsat and AddValue sign significant contract, revolutionising commercial and research-focused satellite operations via the Inter-Satellite Data Relay System
28 June 2018: An agreement signed today by Inmarsat, the world’s leading mobile satellite communications company, and flight hardware manufacturer AddValue, together with a leading satellite operator, is set to streamline the way satellite operators conduct their commercial and research operations with small, near earth orbit satellites.

The agreement will allow the spacecraft to stay in continuous communications with their operation centre on the ground, thereby enabling mission tasking and mission data delivery in near real time. This agreement heralds the first constellation of Inter-Satellite Data Relay System (IDRS™) equipped satellites, one that will provide a game changing capability for satellite operators.
Previously, low earth orbiting satellite connectivity has been limited to when the spacecraft is within line-of-sight of an Earth station. This delays in-orbit testing, mission control and fault-finding efforts. With IDRS on-board, the satellite operators will have access to on-demand, 24/7, near real-time, two-way IP-based links to all of their assets. This will allow them to respond to customer requirements and to operational anomalies in a timelier manner.
Addvalue has worked with Inmarsat to develop a terminal suitable for deployment on a wide range of satellites, even down to small satellites within the sub-50 kg class. The Addvalue terminal on-board the satellite will communicate to its operations centre via Inmarsat’s award winning, global network. The highly reliable, global, geostationary network is uniquely suited to delivering the cost effective, low-latency, on-demand data communications system, known as IDRS, to support commercial and scientific missions. The combination of light weight and small form factor on-board equipment plus low cost makes the system perfect for carrying out telemetry, tracking, and command (TT&C) communications and mission tasking, receiving mission data monitoring, trouble-shooting and restoring operations.
Todd McDonell, Vice President of Global Government at Inmarsat, comments on the importance of this partnership: “This service enables the constellation to be controlled and to transfer mission data via Inmarsat’s global geostationary satellite communications network, wherever and whenever required. This will help low earth orbit satellite operators to achieve their mission more effectively and will broaden the capability that they will be able to offer their users. What’s even more exciting is that this is only the first of a set of potential commercial and
