Vehicle tracking system

vehicle tracking system combines the use of automatic vehicle location in individual vehicles with Software That thesis collects fleet data for a comprehensive picture of vehicle rentals. Modern vehicle tracking systems commonly used GPS or GLONASS technology for locating the vehicle, but other types of automatic vehicle rental technology can also be used. Vehicle information can be viewed on electronic maps via the Internet or specialized software . Urban public transit authorities are an increasingly common user of vehicle tracking systems , particularly in large cities.

United States v. Pineda-Moreno

United States v. Pineda-Moreno was a 2010 Ninth Circuit Court of Appeals case regarding the use of GPS devices. The short ruled that a placing has a personal tracking device without a warrant for a suspect’s Fourth Amendment rights, even if the vehicle was parked in the defendant’s driveway at the time the device was placed. The case was reversed and remanded by the United States Supreme Court in light of United States v. Antoine Jones .

Turn-by-turn navigation

Turn-by-turn Navigation is a feature of some GPS navigation devices where directions for a selected route are continuously presented to the user in the form of spoken and visual instructions. [1] The system keeps the user up-to-date about the best route to the destination. [2] Turn-by-turn systems typically use an electronic voice to inform the user whether to turn or left, the street name, and how much distance to the turn. [3] Continue reading “Turn-by-turn navigation”


Tsikada ( Russian : Цикада meaning cicada ), is a Russian satellite navigation system including ten Low Earth Orbit (LEO) satellites. It transits the same two carrier frequencies as the US TRANSIT satellite system. [1] The first satellite was launched in 1974. [1] Continue reading “Tsikada”

Transit (satellite)

The Transit System, also known as NAVSAT or NNSS (for Navy Navigation Satellite System ), was the first satellite navigation system to be used operationally. The system has been used by the US Navy to provide accurate information on its polaris ballistic missile submarines , and it was also used as a navigation system by the Navy’s surface ships , as well as for hydrographic survey and geodetic surveying . Transit provided by the Department of National Defense.

The Timing satellites were conceived, developed, and launched by the Naval Research Laboratory in Washington, DC, in 1964. The concept of timing was to broadcast an accurate time for use as a ranging signal to receivers on the ground. On 31 May 1967 the Timation-1 satellite was launched. This was followed by the Timing-2 satellite launch in 1969. The results of this program and the Air Force Project 621B formed the basis for the Global Positioning System (GPS). The Navy’s contribution to the GPS program continued to be focused on ever more accurate clocks. [1] Continue reading “Timation”
