According to a news report,“Sprut-N1 [a] new-generation precision navigation radio system (RNS) has been created for the Russian Navy. It will determine geographic location, speed and altitude with a precision superior to that of GLONASS and GPS. The coordinates are determined by ground stations of the system which transmit coded signals to warships and aircraft. The main advantage against satellite navigation is that the signal of the high-tech system cannot be jammed, the Izvestia daily writes.”

In a recently published patent, electric car maker Tesla outlines plans to develop a software that aims to use other vehicles on the road as Earth-based GPS satellites. Such a system would allow Tesla to improve its fleet’s positioning accuracy, even in areas where GPS signals are usually compromised, according to the company.

WASHINGTON – The GPS Innovation Alliance (GPSIA) issued the following statement, commemorating the 25th anniversary of the Federal Aviation Administration’s (FAA’s) certification of the Garmin GPS 155, a device that for the first time enabled pilots to use Global Positioning System as their primary navigation source across all phases of flight — including approach to landing in poor weather conditions. Members of the public may view the prototype, as part of the Time and Navigation exhibition at the National Air and Space Museum.

Designed to support the Indian NavIC (formerly IRNSS) constellation L5 signal simultaneously with GPS L1 and SBAS, the Telit SL869T3-I GNSS module is the new multi-constellation member of the company’s SL869 family of modules.
The SL869T3-I is equipped with special HW and SW to support navigation on L1 and L5 bands. It can navigate using GPS L1, IRNSS/NavIC L5 and the GAGAN L1 SBAS systems concurrently, according to the company.

Two recent reports have underscored the threats to the GPS system from space-capable adversaries. Both the Worldwide Threat Assessment, released Jan. 30 by the Senate Select Committee on Intelligence, and theDefense Intelligence Agency’s newly released Challenges to Security in Spacedetail the potential for China, Russia and others to damage the constellation or disrupt its signals.
With worries mounting about these risks, and the more mundane but still harmful prospect of regional jamming or spoofing, organizations throughout the U.S. government are working on ways to address vulnerabilities and find ways to operate without GPS.
