STAR SERIES
The STAR series offers superior time and frequency synchronization in a minimal space and at a ultra low cost.
Based on a state-of-the art GPS receiver, the Clock delivers 1PPS, 10 MHz and time-of-day outputs with the highest levels of accuracy and stability.
Various levels of configurations are available to easily adapt to the requirements of your Base Stations, Broadcast Station systems, and sub-systems for a discrete and cost optimized synchronization solution.
When no valid input is available, the GPS Clock enters into holdover mode and is specially designed to hold its output frequencies to supply long hours of frequency and phase accuracies.
When enhanced with OSA’s advanced Aging and Temperature Drift Compensation (ATDC) system, the GPS Clock is the most stable GPS quartz clock available in holdover mode. It has a very thin form factor and allows for large temperature variations and harsh environmental conditions.
The GPS Clock is also fully manageable via user-friendly Configuration Manager software. Furthermore, the OSA OEM GPS Clock is highly reliable and totally maintenance-free.
TSAR SERIES
The TSAR offers combined GLONASS and GPS signal reception to supply highly reliable synchronization clock from the two world's two largest Global Navigation Satellite Systems (GNSS), thanks to a state-of-the art 24-channel receiver.
In addition to GNSS, the TSAR offers a 1PPS input to cascade time and frequency from a single antenna to several boards, avoiding the installation of multiple antennas.
Different Oscilloquartz' crystal oscillators can be mounted on the TSAR board to provide the most cost-effective solution to meet the highest adapted holdover performance requirements of any Base Stations, Broadcast Station and sub-systems.
Four 1 PPS and four 10 MHz outputs deliver time and frequency, thereby avoiding a costly and noisy distribution / amplification stage with the host equipment.
Enhanced with its optional Aging and Temperature Drift Compensation (ATDC) system, the TSAR becomes the most stable GPS quartz clock in holdover mode ever, especially in large temperature variations environments and harsh conditions.
A comprehensive command set via an RS232 serial line is available for the TSAR management, allowing alarm reporting, full equipment control and easy integration into the host system.
