Details Emerge On Ligado Decision Delay

The chairman of the Federal Communications Commission (FCC) told two U.S. Senators in January that his agency could not complete a decision on Ligado Network’s license modification by the end of 2019 because of a late-in-the-year response from a key federal agency.

Characterizing GNSS Interference from Low-Earth Orbit

2017 and 2018 saw unprecedented GNSS interference activity, from the eastern Mediterranean to Norway and Finland. Syria emerged as a testbed for electronic warfare capabilities. In April 2018, General Raymond Thomas, commander, U.S. Special Operations Command, referred to the region as “the most aggressive electronic warfare environment on the planet.”

GPS Has Role in Probing Universe’s Mysteries

International astronomers linked observations from eight telescopes, including the the Canadian Hydrogen Intensity Mapping Experiment (CHIME), to pinpoint the location of a repeating fast radio burst (FRB), a little-understood and seldom-observed astronomical phenomenon that may hold keys to the origin of the universe. GPS played an important role in coordinating the telescopes and their milliseconds of data.

Bootstrapping Location for Army Patrols

Forward-deployed U.S. military personnel will soon benefit from warfighter localization sensor units that provide tracking information in GPS-denied environments in a bootstrap mode. The Army Product Manager Sets, Kits Outfits and Tools awarded a $16.5 million contract to Robotic Research of Clarksburg, Maryland for WarLoc units to equip four deployed U.S. Army Brigade Combat Teams in various locations. The first batch of systems has already been shipped, and should enable soldiers on foot to keep track of each other in terrain where GPS systems are less effective.

WarLoc provides localization and positioning data for teams of warfighters or first responders in signal-denied environments such as underground facilities and inside buildings and mega-cities, according to the company. The small sensor mounts on footwear. Multiple systems work together to further enhance accuracy and maintain the localization of teams.

The tracking system augments its GPS receiver with an inertial measurement unit. The device connects with a smartphone through Bluetooth. Robotic Research fields two form factors of the WaLoc, one mounted over the top of the boot and another that wraps around the heel. Users view data readouts through an Android-based Tactical Assault Kit. The algorithms are reportedly robust to communications failures and dropouts, and the distributed nature works well in challenging communication environments.
