Global Navigation Satellite Systems Engineering, Policy, and Design
Miguel Manteiga BautistaThe first generation of the Galileo Program, at satellite and ground segment level, has been “an enormous success,” according to Miguel Manteiga Bautista, who recently spoke with Inside GNSS at his office at the European Space Agency’s European Space Research and Technology Centre (ESTEC) in Noordwijk, Netherlands.

Speakers at the 9th Annual Conference on European Space Policy wasted no time in addressing the somewhat worrying failure of several 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.

Figures and ChartsThe GPS community and Virginia-based Ligado are weighing new and upcoming test results as the standoff over interference with satellite navigation services enters its seventh year.
The dispute centers on the company’s now modified proposal to build a terrestrial wireless network supported by frequencies originally allocated for satellites. Though there had been a move some years earlier to augment the satellite services with ground stations the company’s first plan envisioned some 30,000 high-powered ground terminals.

The new HPL service will use real-time kinematic- (RTK-) based solutions for augmentation of high-precision receivers, said Tamara Casey, Ligado’s chief technology officer, during Satellite 2017.

With expectations including the delivery of better accuracy and improved resilience to EGNOS performance, there’s plenty of excitement surrounding the development of EGNOS V3.
A big step toward this development was taken when the European Global Navigation Satellite Systems Agency (GSA) selected Eutelsat Communications for the development, integration and operation of the next-generation EGNOS payload on a future Eutelsat satellite.

The entrepreneurial space launch firm SpaceX won a head-to-head competition with United Launch Alliance (ULA) to secure its second GPS launch contract.
The launch of the GPS III spacecraft onboard a Falcon 9 rocket is expected to take place in 2019. The $96.5 million deal was officially announced March 14.

Pierre Delsaux speaks at the Munich Satellite Navigation Summit. Photo: Peter Gutierrez.The opening plenary of the annual Satellite Navigation Summit in Munich tends to be a ritzy affair, taking place in the evening in an amazing converted chapel and featuring live musical interludes in between groups of speakers. This year the audience was treated to movie tunes, and the European Commission’s Pierre Delsaux had a suggestion for the play list.
