Inmarsat grants free satellite use for Geostar experiments
2.10. INMARSAT GRANTS FREE SATELLITE USE FOR GEOSTAR EXPERIMENTS”*’
Inmarsat will provide free capacity on one of its satellites to the US Geostar Corporation for tests and demonstrations of a land mobile position reporting and communication satellite service. The request for experimental capacity was received by Inmarsat from its US Signatory member organization, Comsat Corporation. The purpose of Geostar’s proposed experimental programme is “to test the use of satellite communications for position reporting in the land mobile environment”. The test and demonstration will be carried out with 30 vehicle terminals sharing a single L-band to C-band frequency channel in random access mode. The programme is expected to start about the end of 1986. “Inmarsat’s in-principle agreement to this request is in line with its longstanding policy of providing free access to its satellites for experiments which promise the possibility of expanding and improving mobile satellite communications technologies and applications”, Inmarsat’s Director General, Olof Lundberg, said. “This is in fact the 24th programme of this nature supported by Inmarsatl’ However, Mr Lundberg emphasized that, since 1979, Inmarsat and its forerunner Marisat had provided services which had enabled both automatic position reporting via satellite from ships and other mobiles, and the interrogation of mobile position information from customer premises (polling). This service is now widely used by mobiles equipped with Inmarsat Standard-A communications terminals. “With the introduction in the next year or so of Inmarsat’s new low-cost miniature Standard-C communications terminals, we expect the use of the Inmarsat system for this type of application to increase greatly”, he said. “Next year, we shall also conduct experiments, using our satellite system, into position determination by ranging as well as another series of trials in support of other navigation systems”.

The configuration of the new ignition system for the Ariane third stage was approved by the European Space Agency (ESA) and Arianespace on 28 November 1986. This configuration was proposed by the SociCtC Europeene de Propulsion (SEP) following the series of studies and tests carried out since July 1986. This test programme included in particular 23 altitude simulation tests performed on the PF 41 teststand at Vernon near Paris, France. The Enquiry Board set up in June 1986 has expressed a favourable opinion. The (‘*)Extract from hmarsat News Release NR86/32/2846B of 27 November 1986.
