Sensor role reversal: How lidar can replace GNSS for navigation

SIFT_opener-2-O

Airborne lidar/INS/GNSS: Algorithm Uses Fuzzy Controlled Scale Invariant Feature Transform Sensor role reversal: Lidar with its superior performance can replace GNSS in the integration solution by providing fixes for the drifting inertial measurement unit (IMU). Tests show its potential for terrain-referenced navigation due to its high accuracy, resolution, update rate and anti-jamming abilities. A novel algorithm uses scanning lidar ranging... read more

Geoscience Australia, Lockheed collaborate on multi-GNSS SBAS research

February 13, 2017By
To improve precision navigation, a second-generation SBAS will use signals from both GPS and Galileo, and dual frequencies, to achieve even greater GNSS integrity and accuracy.

Geoscience Australia, an agency of the Commonwealth of Australia, and Lockheed Martin have entered into a collaborative research project to show how augmenting signals from multiple GNSS constellations can enhance positioning, navigation and timing for a range of applications. Other partners are Inmarsat and GMV. The research project aims to demonstrate how a second-generation Satellite-Based Augmentation System (SBAS) testbed can... read more

Tracking RFI: Interference localization using a CRPA

Eurocontrol-airtrafficcontroller-airlines-O

A controlled radiation-pattern antenna can preserve GNSS positioning while providing at least an azimuth angle towards an interference source. If integrated with an attitude and heading reference system, only a few lines of position pointing towards the RFI source could provide a fast indication of the probable ground location. read more

Indian government warns airlines to use GAGAN

January 17, 2017By

The government of India has warned domestic airlines of “consequences” if they do not use GAGAN, the state’s GPS-Aided Geo Augmented Navigation system, reports the Mumbai Mirror. The warning came during a meeting called by the Directorate General of Civil Aviation (DGCA) in December with all stakeholders, including the airlines. Most aircraft registered in India are still not equipped with... read more

Silent Falcon UAS Technologies participated in the NASA UTM (unmanned traffic management) project headed up by the NASA Ames Research Center, held this month in Reno, Nevada. NASA and the Federal Aviation Administration (FAA) are working together to identify ways to safely enable large-scale UAS operations in the low-altitude airspace. The growing number of UAS and commercial UAS applications has led... read more
