Presentations and Articles: Combining GPS based Precise Timing and Accurate Navigation Requirements, Benefits

It has been a continuous trend that all aerospace and payload programs require more and more parameters to be measured during flight tests, at increasing sampling rates. Contextual data, associated with measurements – like timestamp, geolocation, attitude - are instrumental to performing a relevant analysis of measured data. Therefore flight test teams, in charge of engineering high speed measurement systems, need to ensure proper time alignment amongst all on-board systems, facing two challenges:

  • Distribute precise time (better than 1 μs), even in case of GPS loss, over the whole test mission duration
  • Distribute precise position and attitude, which are time-stamped consistently with the distributed time

In this paper, we demonstrate how a combined position & attitude measurement sensor and precise time server can meet all “Positioning, Navigation and Timing (PNT)” needs for a complex observation payload like an on-board test system and a SAR imagery radar, with benefits in terms of architecture simplification, and overall performance increase in terms of time and attitude accuracy. We also review the benefits of associating a high stability clock with a GPS receiver, in terms of improvement of some GPS reception performances.

Presentations and Articles: Navigating With More Than Just GPS

The resurgence of the automotive industry has come with strong buyer interest in technology to improve safety, convenience and awareness in the automobile. GPS is one such technology that has strong consumer demand. While a GPS receiver is at the heart of any navigation system, applications for GPS extend to a wide range of automotive systems. Virtually anything with a sensor can take advantage of GPS data such as date, time, precise frequency, altitude, heading, velocity partly because it is very accurate and independent of any other system. But GPS is not the only satellite in the sky anymore. More and more Global Navigation Satellite Systems (GNSS) are being developed and deployed. Receivers are available to make use of multiple systems that, when used together, improves accuracy and reliability.

Presentations and Articles: Zone Based Indoor Location Using GNSS Simulators Signals from Global Navigation Satellite Systems (GNSS), such as the Global Positioning System (GPS), are very weak and usually cannot be seen indoors or underground. A common method to overcome the problem of receiving GNSS signals indoors or underground is to use a GPS/GNSS repeater with an antenna located outdoors to receive the GNSS signals and an amplifier/antenna to re-transmit the signal indoors. This paper describes the technologies and methods for creating an intelligent repeater system including time synchronization at the nanosecond, microsecond, and millisecond levels, how each synchronization level affects the overall system and methods for achieving each, power level considerations including power level requirements between zones and how they affect transitions from one zone to another, data transfer and example system configurations. While GPS is primarily demonstrated and tested, the possibility for adding other GNSS constellations such as QZSS, BeiDou, Galileo, and GLONASS are also presented. pdf - 270 KB

Presentations and Articles: Testing GNSS Receivers to Harden Against Spoofing Attacks Spoofing is an attempt to deceive the GNSS/GPS receiver by broadcasting signals that the receiver will use instead of the live sky signals. This article describes a test system for spoofing allows testing the three major factors to consider in a spoofing attack, time synchronization to the signals to be spoofed, power level of the spoofing signal compared to the live sky signals, and accuracy of the position obtained by the spoofing signal to that of the actual position of the device being spoofed. Using a spoofing test system will allow a user to better understand the receiver and harden the system against spoofing attacks. pdf - 673 KB

Presentations and Articles: GPS/GNSS Spoof Testing By Simulation

Hardening GPS/GNSS receivers against spoofing and jamming is crucial as threats are new, real and increasing. Testing with a GPS/GNSS simulator is a very effective tool for designing and evaluating countermeasures for mission-critical applications for positioning, navigation and timing. This presentation describes the application for testing spoofing.
