CTL460 GPS Timing Module
Ultra high sensitivity assisted GPS technology
The CTL46x series GPS Timing Modules from Chronos are designed for where a low cost source of highly accurate time is required, in a very small form factor. The series can be specified with the latest Chip Scale Atomic Clock (CSAC) from Microchip for extended holdover, or with TCXO oscillator for reduced holdover and lower cost applications.
Fitted with a multi-constellation GNSS receiver that can track GPS, GLONASS, Galileo, BeiDou and QZSS, the CTL46x series utilises the very latest state of the art GPS technology that allows ultra high sensitivity satellite tracking to levels as low as –160dBm. This low strength signal capability can enable GPS timing in very weak signal areas such as under dense foliage, in severe urban canyons and even inside buildings.
The CTL46x provides 1pps and 10MHz output signals and includes the capability to perform a self survey and enter a fixed position mode of operation. This allows GPS timing with only one satellite being tracked as low as –160dBm thereby greatly extending the ability of the unit to output GPS steered time and reducing holdover requirements. In addition, the unit will autonomously scale the self survey window based on initial reported GPS position to allow entry into fixed position mode even in very weak signal areas.
