The New Flex Power Mode: From GPS IIR-M and IIF Satellites with Extended Coverage Area

GPS satellites usually transmit their signals with constant power. However, a so-called “Flex Power” is foreseen to increase the strength of individual signals to better fulfill operational constraints. Flex power operations can be detected in carrier-to-noise density ratio (C/N0) observations provided by GNSS receivers of the global tracking network of the International GNSS Service (IGS).

Knives Out

The Federal Communications Commission should really consider updating its motto. “Firm, fast, flexible, and fair” has a bit of an old-fashioned ring. As mottos go, it fails to keep up with the times.

Photonic Technology Brings a Cutting Edge to Inertial

Order-of-magnitude advances in inertial technology seem to take place roughly every 20 years, and the industry is poised at such a point now. New developments in photonic technology make high-performance inertial measurement accessible at lower size, weight and power. Many applications from driverless cars to UAVs can now take advantage of positioning that can independently bridge GPS outages from 2 minutes up to 10 minutes.

Receiver with Inertial for UAVs

A new GNSS/INS receiver, the AsteRx-i D UAS from Septentrio, specifically targets integration into unmanned aerial systems (UAS).  It provides centimeter-level RTK positioning and 3D attitude. It features a 44 pin connector compatible with 3rd-party integrations, as well as event marker inputs to accurately time-stamp camera shutter events.
