Cyber Attack Disables Private Pilots, GPS Fitness Users

Hackers exposed another vulnerable chink in U.S. national infrastructure over the weekend, in an attack on GPS manufacturer Garmin that began late Thursday, July 23.  Although the cybersecurity strike, apparently aimed at extorting a ransom, did not explicitly include the GPS signal, it disabled two large GPS user communities: general aviation (private pilots and some larger commercial flight operators) and fitness enthusiasts. Both found their Garmin devices and apps unresponsive.

Silicon MEMS Accelerometer: the Latest Disruptor

MEMS has moved into the high-end market, and the latest disruptor to take into account is silicon MEMS. That’s micro-electromechanical systems based in silicon chips, for short. Accelerometers with up to 100g range and 70µg bias in a very small form factor — 6 cubic centimeters — are exploding the horizons for inertial applications.

Magnetic Sensors in Flight Tests as Alternative PNT to GNSS

A new magnetic anomaly navigation technique (MAGNAV), researched by the Air Force Institute of Technology (AFIT), will get its wings tested aboard F-16 fightercraft this September. In an effort seeking alternatives to GPS and GNSS, MAGNAV sensors and software will be flown on Air Force Test Pilots School (AFTPS) F-16s over a test range adjacent to Edwards Air Force Base in Nevada.

Satellite Visibility to Aid Claus Mission

In lead position on a sleigh rising from the North Pole to a height of 200 meters — standard cruising altitude for global package delivery — at 2100 hours UTC on December 24 — the youngest will hopefully be asleep by then and there’s plenty of territory to cover before dawn breaks, time’s a-wasting — navigator Rudolph will see between 40 and 45 GNSS satellites glistening in the night sky.

GBAS Installations Will Proceed at Airports Across Europe

A European aviation industry alliance will deploy new-generation GNSS-based landing systems, ground-based augmentation systems or GBAS, at airports across the continent, starting this year and gaining momentum in 2020. The GBAS Alliance includes airlines and aircraft manufacturers who will complementarily equip their planes with GBAS reception equipment. GBAS is recognized as a supplement to and future replacement of instrument landing systems (ILS).

Portable, Rapid-Install Precision Lander Enables Remote Operations

A portable differential GPS-based precision landing system that guides aircraft in to spot landings in all weather, challenging terrain and surfaces conditions proved itself in a rapid set-up demo before military officials of five countries recently. A Raytheon team set up the company’s Joint Precision Approach and Landing System (JPALS) in less than an hour on a small footprint and promptly brought in multiple F-35Cs, long-range stealth strike fighters, to the same designated runway landing point every time over the course of six different approaches.

Israel Aerospace Industries Unveils ADA-O to Enable Land Platforms to Deal With GNSS Anti-Jammers

Israel Aerospace Industries (IAI) is introducing ADA-O, an additional development in the ADA lineup, which addresses GPS jammers to ensure GPS availability for land platforms. The land platform can be readily integrated in a range of platforms, providing a unique operational response to help telecom, navigation and C&C systems. Easily installed and integrated on the end-user platform, it serves end users on armored vehicles, artillery, C&C centers and communication carriers, according to IAI.
