Galileo Teams Investigating ‘Injection Anomaly’ of FOC Satellites

European Space Agency (ESA) and industry officials said today (August 23, 2014) that they are investigating Arianespace’s announcements about anomalies in the orbit injection of the Galileo full operational capability (FOC) satellites launched Friday.

“Complementary observations gathered after separation of the Galileo FOC M1 satellites on Soyuz Flight VS09 have highlighted a discrepancy between targeted and reached orbit,” according to a Friday statement by Arianespace, which leads the industry team handline the launch of the first Galileo FOCs.

Europe Puts First FOC Satellites into Orbit

After 20 years of discussion, conceptualization, political struggle, and technical reverses, Europe has placed its first two fully operational capability (FOC) Galileo satellites into orbit today (August 22, 2014).

The Galileo 5 and 6 satellites were carried aloft on a Soyuz rocket from Europe’s Spaceport in French Guiana at 12:27 GMT (14:27 CEST, 09:27 a.m. local time). They join the Galileo in-orbit validation (IOV) satellites 1–4, one of which has been offline since May.

Weather Delays Galileo Launch

Due to unfavorable weather conditions of the Guiana Space Center near Kourou, French Guiana, Arianespace decided to postpone the launch scheduled for today (August 21, 2014) of Soyuz flight VS09 carrying Europe’s fifth and sixth Galileo satellites — and the first of the fully operational capability (FOC) spacecraft.

A tropical disturbance in the Atlantic Ocean nearing the Lesser Antilles (see NOAA satellite image) could potentially developed into a tropical depression or tropical storm.

As Galileo FOCs Near Launch, EC Holds Public Consultation on Open Service ICD

Installation of Galileo FOC satellite “Doresa” on the payload dispenser system. The first of two Galileo navigation satellites has been integrated on its payload dispenser system at Europe’s Spaceport in Kourou, French Guiana. The second satellite “Milena” was then installed in a side-by-side arrangement and will be mated atop a Soyuz Fregat upper stage. ESA/CNES/Arianespace/Optique Vidéo du CSG photo by P. Baudon

The European Commission (EC) has opened a public consultation on a newly revised version of the Galileo Open Service Signal in Space Interface Control Document (OS SIS ICD).
 
The consultation will take place through September 22, overlapping the scheduled first launch of fully operational capability (FOC) Galileo satellites on August 21. Details of the consultation process can be found on the EC Directorate-General for Enterprise website.

Galileo Team Reports Successful Tracking of Encrypted Commercial Service Signals

The European GNSS Agency (GSA) announced today (July 29, 2014) that a recent 10-day test has successfully tracked and demodulated data from encrypted signals of the Commercial Service (CS) from available Galileo satellites.

Using receivers located in Tres Cantos, Spain, and Poing, Germany, the Early Proof of Concept (EPOC) team tracked encrypted Galileo E6-B and E6-C signals. Non-encrypted E6-B and E6-C signals have previously been tracked.

GNSS Position Estimates

Q: How do measurement errors propagate into GNSS position estimates?

A: Not surprisingly, GNSS positioning accuracy is largely dependent on the level of measurement errors induced by orbital inaccuracies, atmospheric effects, multipath, and noise. This article discusses how, specifically, these errors manifest as position errors.
