Stockholm — Pendulum Instruments, an Orolia Group company, has introduced a combined GPS and GLONASS controlled frequency standard designated GPS-12RG. The frequency standard combines the two major timing and navigation satellite systems, GPS and the Russian GLONASS, to improve the precision and signal coverage.
The instrument is a further development of the company's successful GPS-12R which uses the GPS satellites to control its output frequency. The GPS-12RG can trace its operation to both GPS and GLONASS satellites, and contains a very-high stability Rubidium atomic clock. It is a compact one-box-solution, containing also an optional internal battery for use as UPS backup power on the bench, for warm-keeping of the oscillator during transport or for mains-free operation in the field.
The internal Rubidium oscillator gives excellent stability of a few parts in 10-12, also in hold-over operation, for example when satellite contact is lost. It can be used as a very accurate frequency calibrator for calibration labs, institutes, electronics and in telecommunications.
The instrument is available for deliveries in May/June, 2008.
