Family tracking app leaked real-time location data for weeks - Engadget Mar 2018
"Family tracking apps can be very helpful if you're worried about your kids or spouse, but they can be nightmarish if that data falls into the wrong hands. Security researcher Sanyam Jain has revealed to TechCrunch that React Apps' Family Locator left real-time location data (plus other sensitive personal info) for over 238,000 people exposed for weeks in an insecure database. It showed positions within a few feet, and even showed the names for the geofenced areas used to provide alerts. You could tell if parents left home or a child arrived at school, for instance."

"While the data is safe for now, the incident illustrates a problem with tracking apps as a whole: it's difficult to verify that developers are securing your location info every step of the way. If they don't and there's a breach, it could lead to very real threats that could include physical danger."

Air Force experiment NTS-3 could point the way to the next generation of GPS - SpaceNews.com Mar 2019
"As an immediate response, the Air Force has begun deploying more-advanced GPS satellites, called GPS 3, designed to be more resistant to jamming and spoofing.

The Air Force also is looking for ways to shore up the PNT capabilities provided by GPS. One approach the Air Force believes could work is to supplement its medium Earth orbiting GPS constellation with an additional layer of smaller satellites in geosynchronous Earth orbit.

To test that idea, the Air Force Research Laboratory in 2022 will launch an experimental PNT satellite called NTS-3, short for Navigation Technology Satellite 3."

"As the U.S. military’s first Navigation Technology Satellite mission in 40 years, NTS-3 is intended to test new hardware including a digital signal generator that can be reprogrammed on orbit, enabling operators to quickly deploy new signals as they encounter electronic threats."

"The Air Force still has 31 GPS 2 satellites in service and has only just begun to deploy its GPS 3 constellation. "

How to choose the best GPS for your iPad - iPad Pilot News
Our picks

Which one is best for pilots? None of these GPSs is really a bad choice, but we’ll offer two picks. For a good performer at a good price, the Dual XGPS150A is hard to beat. At just $99.95, it offers good battery life, reliable performance and a handy dash mount. It has been one of the best-selling models for years and gets good reviews from pilots.

For a deluxe model, or for pilots who fly with multiple devices in the cockpit, we like the new Bad Elf Pro+. At $249.99 it isn’t cheap, but it’s very well made and has a number of great features: an incredible 35-hour battery life, handy built-in screen, altimeter and connection to multiple devices.

You can see the entire selection of iPad GPSs at Sporty’s.

“Recalculating Route”: A Realistic Risk Assessment for GPS
Complete denial of GPS — via kinetic or cyber attack — while maybe technically possible, is implausible as it would connote an enormous, perhaps even apocalyptic, escalation.
