DEVELOPING GNSS-RECEIVER FOR SCIENTIFIC APPLICATIONS

The Namuru Receiver as Development Platform for Spaceborne Gnss Applications

GPS is a well established navigation system in current spaceflight missions. Affordable GPS receivers for small satellite and sounding rocket missions are usually based on Commercial Off The Shelf (COTS) products. Many of these receivers are limited to single frequency tracking and utilise custom ASICs for the signal processing. The Phoenix receiver is an example of a commercially available rec...

Multi-gnss Receiver for Aerospace Navigation and Positioning Applications

The upcoming Galileo system opens a wide range of new opportunities in the Global Navigation Satellite System (GNSS) market. However, the characteristics of the future GNSS signals require the development of new GNSS receivers. In the frame of the REAGE project, DEIMOS and ISEL have developed a GNSS receiver targeted for aerospace applications, supporting current and future GPS L1 and Galileo E...

Spaceborne Receiver Design for Scatterometric GNSS Reflectometry

GNSS - based Positioning Map Data Base EGNOS data GNSS Receiver

This paper describes a new Map-Matching method relying on the use of Particle Filtering. Since this method implements a multi-hypothesis road-tracking strategy, it is able to handle ambiguous situations arising at junctions or when positioning accuracy is low. In this Bayesian framework, map-matching integrity can be monitored using normalized innovation residuals. An interesting characteristic...
