Advisory Board Invites Ligado to the Podium

The nation’s leading satellite navigation experts have invited Ligado Networks, a firm whose plans are widely viewed by many as a threat to satnav, to present at their November 15 meeting. If the company accepts, it could illuminate the structure of the terrestrial service it has in mind and either ease, or add fuel to, the ongoing dispute between Ligado and the GPS community.

Tallysman announced that Facebook has selected the Ottawa, Canada company’s TW2643POC GPS/Iridium antenna for the Facebook Open Cellular Platform.

The TW2643POC employs Tallysman’s unique Accutenna technology in a magnet mount, passive right hand circularly polarized antenna for the reception of all of the GNSS constellations (GPS L1/GLONASS G1/ Galileo E1/ BeiDou B1) plus Iridium: 1559 to 1626.5 MHz frequency band. It is certified and specially designed to maximize the performance of Iridium Voice and Data Modems plus the upper GNSS band (1559 – 1606MHz).

Speakers at last month’s 9th Annual Conference on European Space Policy in Brussels wasted no time in addressing the somewhat worrying failure of a number of Galileo onboard clocks, as revealed by European Space Agency Director General Johan-Dietrich Woerner at a press briefing earlier in January in Paris. He made clear at the time that the clock failures, while indeed troubling, had had no effect on the operational integrity of the Galileo system.
