Global Navigation Satellite Systems Engineering, Policy, and Design
In September, the Agency for Air Navigation Safety in Africa and Madagascar (ASECNA) started broadcasting a satellite-based augmentation system (SBAS) signal over Africa and the Indian Ocean. This marks the first SBAS open service in the region, modeled based on the European Geostationary Navigation Overlay Service (EGNOS).

Six months ago, the FCC unanimously granted Ligado’s amended license modification applications to deploy a low-power terrestrial nationwide network in the L-Band. Petitions for reconsideration remain pending, interest groups continue to agitate for change, Congress awaits answers to conflict-of-interest questions—and Ligado presses forward as planned.

A broad cross-industry coalition sent a strongly worded letter to the Senate Commerce Committee warning that the Federal Communications Commission’s (FCC’s) Ligado Order that impacts GPS, if left in place, “would upend decades of sound spectrum policy, negatively impact a significant cross-section of commercial, federal, and academic users who rely on the many different L-band satellite services, and threaten the safety of most Americans.”

Collins Aerospace received a program-of-record contract to mature and integrate a positioning, navigation and timing system for the U.S. Army’s for the Army’s increasingly sophisticated manned ground vehicles. The Mounted Assured Position Navigation and Timing System (MAPS) will maintain the integrity of positioning and timing during operations in GPS-contested environments.

Laboratory tests explore how commercially available receivers respond to meaconing and spoofing, with the goal of developing useful test methodologies and metrics to assess receiver robustness and resilience to real-world spoofing threats.
The fifth GPS III satellite rising in 2021 will ride aboard a previously used Falcon 9 first-stage booster, in a first for a National Security Space Launch mission. Space Exploration Technologies Corporation (SpaceX) has contracted with the U.S. Space Force’s Space and Missile Systems Center Launch Enterprise to reuse the booster rockets.

The Russian Defense Ministry has publicized tests of its new Tornado-S precision missile, which takes GLONASS data input for its target and flies in squads capable of taking out dispersed enemy formations. The missile comes in a multiple launch rocket system (MLRS) that can fire up to 12 missiles simultaneously in a coordinated attack.
