During the test campaign of the EPOC (Early Proof-Of-Concept) in the frame of the AALECS (Authentic and Accurate Location Experimentation with the Commercial Service) project, magicGNSS reference products have been broadcast in the Galileo E6 signals.

Orbit and clock predictions have been generated 2-3 days in advance of each test by magicODTS using data gathered by the IGS MGEX network (http://igs.org/mgex/). This high-accuracy (HA) data is then sent to GMS and uploaded to the IOV satellites for broadcast during test slots (see figure below).

The E6-B signal has been tracked both with SCE (Spreading Code Encryption) enabled and disabled. During tests broadcast products are gathered and authenticated via TESLA-based NMA and/or SCE. Then, a high-precision data-authenticated PVT solution is computed by means of magicPPP.

The aim of the test campaign has been to evaluate the E6 data transmission performance, and prove that the system is capable of providing authentication and HA positioning/timing services. Several static and kinematic tests have been conducted from mid-July to late-September 2014. The figure below shows performance of a static PVT with SCE enabled: an RMS below 40 cm in the horizontal plane is achieved, including the convergence period.

In the previous entry I explained how to upload and share your own station data in magicGNSS. The first public station in magicGNSS is called gap1, uploaded by myself (rpiriz).

The gap1 station is located in our offices in Tres Cantos, Madrid, Spain. A Septentrio PolaRx2 GPS receiver, connected to a Temex iSource LPFRS Rubidium atomic clock, is permanently running in our lab. The receiver is controlled by a dedicated PC under GNU/Linux.

We have just released magicGNSS version 1.0 (not a Beta anymore!) You can have a look at the brochure we have prepared for the new product.

One of the things you can do with the new magicGNSS 1.0 is to upload and share your own station data (as a *pro* user only). If you share a station other users will be able to process its data in PPP and ODTS. If you want to share your station data, just click on the Share checkbox in My Stations:

As from today we are moving to a new core station data management approach. We realize that in general for the user it is more useful to have recent data from many stations and with as little latency as possible. Unfortunately keeping old data from many stations on the magicGNSS server takes a lot of disk space (typically each station takes around 80 Mb of uncompressed RINEX data per day).

Until now we kept on the server core station data starting from July 1st 2008, to current time. As from now we will keep a moving window of one-month duration, i.e., the last 30 days of data will be always available on the server, and older data will be automatically deleted.

Today we make magicGNSS Beta available to everybody!

magicGNSS Beta is the first available version of our suite of GNSS algorithms and products. With this beta, you can do precise Orbit Determination and Time Synchronisation (ODTS) of GPS satellites, using data from a network of Core Stations available in near real time. The results include satellite orbit estimations and predictions, station and satellite clock estimations, station coordinates and tropospheric zenith delays.

In a few easy steps you will be able to configure and run a scenario. After a few minutes, the execution will conclude and you will be able to download the results and a comprehensive report of the outputs.
