2. Spoofing attack - Wikipedia

   en.wikipedia.org/wiki/Spoofing_attack

   In June 2017, approximately twenty ships in the Black Sea complained of GPS anomalies, showing vessels to be transpositioned miles from their actual location, in what Professor Todd Humphreys believed was most likely a spoofing attack. [27] [30] GPS anomalies around Putin's Palace and the Moscow Kremlin, demonstrated in 2017 by a Norwegian ...

3. Selective availability anti-spoofing module - Wikipedia

   en.wikipedia.org/wiki/Selective_availability...

   A Selective Availability Anti-spoofing Module (SAASM) is used by military Global Positioning System receivers to allow decryption of precision GPS observations, while the accuracy of civilian GPS receivers may be reduced by the United States military through Selective Availability (SA) and anti-spoofing (AS). [1]

4. Stingray phone tracker - Wikipedia

   en.wikipedia.org/wiki/Stingray_phone_tracker

   Cell phones are programmed to connect with the cellular tower offering the best signal. When the phone and Stingray connect, the computer system determines the strength of the signal and thus the distance to the device. Then, the vehicle moves to another location and sends out signals until it connects with the phone.

5. Comparison of free off-line satellite navigation software

   Very basic programs like this may not be suitable for road navigation in cars, but serve their purpose for navigation while walking or trekking, and for use at sea. To determine the GPS coordinates of a destination, one can use sites such as GPScoordinates.eu and GPS visualizer. Some software presented here is free, but maps may need to be paid ...

6. IMSI-catcher - Wikipedia

   A virtual base transceiver station (VBTS) [5] is a device for identifying the temporary mobile subscriber identity (TMSI), international mobile subscriber identity (IMSI) of a nearby GSM mobile phone and intercepting its calls, some are even advanced enough to detect the international mobile equipment identity (IMEI).

7. GPS jamming - Wikipedia

   en.wikipedia.org/wiki/GPS_jamming

   GPS jamming is a particular type of GNSS interference. Under ITU rules, countries are obliged to eliminate harmful interference through GPS jamming and spoofing, but the ITU lacks effective enforcement measures. [2] The ICAO legal framework requires that countries should implement appropriate prevention and mitigation of GPS jamming and ...

8. Receiver autonomous integrity monitoring - Wikipedia

   en.wikipedia.org/wiki/Receiver_Autonomous...

   The integrity of received signals and resulting correctness and precision of derived receiver location are of special importance in safety-critical GNSS applications, such as in aviation or marine navigation. The Global Positioning System (GPS) does not include any internal information about the integrity of its signals. It is possible for a ...
