SINGAPORE (Aug 11): Addvalue Technologies, the developer and supplier of mobile satellite terminals, has formalised a worldwide agreement with UK-listed Inmarsat to jointly offer its Inter-Satellite Data Relay Service (IDRS) to the Low Earth Orbit (LEO) satellite market.

The Inmarsat and Addvalue IDRS service agreement comes after the two companies signed a memorandum of understanding, which was announced by Addvalue this year on Feb 2.

In a Friday news release, Addvalue says IDRS will be based on its space-tested IDRS terminal as well as Inmarsat’s Geosynchronous Earth  Orbit (GEO) I-4 satellite-based Broadband Global Area Network (BGAN).

With the latest agreement, IDRS will be available to carefully-targeted commercial LEO customers globally, whilst the two companies will work together to take the service to market – with Addvalue providing the IDRS flight hardware to be carried on board the LEO satellites, as well as serving as the distributor of IDRS airtime to LEO satellite operators.

The company is in the view that the IDRS will significantly enhance and improve the operational efficiency of LEO satellite operations globally, as the “world’s first commercial on-demand communications service specifically designed to address certain elements of the rapidly-expanding LEO satellite market”.

This is because with IDRS, LEO satellite operators will be able to benefit from on-demand 24/7, near real-time two-way IP-based communication links to all of their satellites. The service will also allow LEO constellation operators to rapidly respond to customer requirements, and to operate anomalies in their fleet.

Prior to the introduction of IDRS, communications with LEO satellites was only known to be available only when the satellite was within line-of-sight of an earth station, says Addvalue.

“We are delighted that our years of hard work have resulted in our partnering with Inmarsat to offer this communications service. Catering to the fast growing LEO satellite market is an exciting business opportunity for us,” says Colin Chan, chairman and CEO of the group.

“Furthermore, this will enable us to extend our marketing to include IDRS airtime that has great upside potential for Addvalue. Inking this agreement will enable us to move forward commercial discussions with our customers,” he adds.

As at 9:47am, shares in Addvalue are trading 2% lower at 4.8 cents.
