ZeroTrace GPS & BeiDou Jammer for Vehicles

Vehicle-Focused Satellite-Signal Interference

ZeroTrace is a compact jammer designed to interfere with GPS L1 and L2 reception, with support for BeiDou also listed. It works on satellite-navigation reception within a stated range of 5–10 meters; actual coverage depends on the receiver and surrounding conditions.

The listed frequency ranges are 1500–1600 MHz for L1 and 1200–1300 MHz for L2. BeiDou is a satellite-navigation system used for positioning, navigation, and timing. Receivers may use more than one navigation system, so interference with the listed signals does not establish that every form of location tracking will stop.

Three Power Options for Vehicle Applications

The 240 g unit can run from a 5 V USB supply, its built-in rechargeable battery, or a compatible vehicle OBD power connection. External power supports extended operation while a suitable supply remains available.

Battery life is up to 2 hours under ideal conditions. Actual runtime varies with use. The OBD connection serves as a power option; confirm the appropriate connection for your vehicle and supplied configuration.

How BeiDou works

BeiDou is China’s global navigation satellite system, or GNSS. Like the U.S. GPS system and Europe’s Galileo, it provides positioning, navigation and timing services. China developed the network to establish its own independent satellite navigation infrastructure.

The name BeiDou (北斗) refers to the Big Dipper, the seven-star pattern within the constellation Ursa Major. The system expanded from regional service to worldwide coverage with BeiDou-3, completed and commissioned in 2020.

Satellites broadcast their position and precise timing information. A receiver uses the signals’ travel times to estimate its distance from each satellite, then calculates its location. A standard three-dimensional position fix normally requires at least four satellites to resolve position and the receiver’s clock error.

This process uses distance measurements rather than angles. It is the same basic positioning principle used by other global satellite navigation systems.

Coverage, compatibility and everyday uses

Compatible multi-GNSS receivers can use BeiDou alongside GPS, Galileo and GLONASS. Access to more satellites can help maintain a position fix when buildings or other obstacles block part of the sky. Support depends on the receiver and the signals it can process.

BeiDou also provides regional services in the Asia-Pacific area. That does not make it universally more accurate than GPS: real-world performance depends on satellite geometry, reception conditions, signal selection and receiver quality.

Common uses include vehicle navigation and tracking, smartphone maps, fleet management and transportation. Positioning and timing services support applications across road, maritime and aviation operations.

BeiDou serves civilian users as well as government and defense applications, with different services and access arrangements. For a specific device, check its supported constellations and signals rather than assuming that every GNSS receiver supports BeiDou.
