Some radio clocks and related timekeeping gear have a pulse-per-second (PPS) signal that can be used to discipline the local clock oscillator to a high degree of precision, typically to the order less than 10ms in time and 0.01 parts-per-million (PPM) in frequency. The PPS signal can b...
The invention provides a pulse per second (PPS) signal generating device for vehicle-mounted equipment. The PPS signal generating device comprises a hardware part and control software, wherein a constant-temperature crystal oscillator, an external error signal interface, calibrated equipment, and a ...
1,Based on Central China Power System Stability Control Device, the paper presents the receiving process of GPS timing signal, synchronized sampling from different areas under the control of GPS PPS ( pulse per second), the hardware interface and the access format for data exchange amo...
Pulse per second (PPS) is the simplest form of synchronization. PPS is a signal that outputs a high logic level once a second. It does not contain information about the specific time of day or year. The pulse width is
GNSS receivers are often integrated with other sensors such as inertial navigation system (INS) and camera. The pulse per second (PPS) signal from GNSS rec
6.A clock signal with 1 million pulses per second is referred to as a 1 megahertz.每秒钟有一百万个脉冲及时钟信号,也称兆赫. 7.We waited as the clock ticked away the last few seconds of the old millennium.我们静候着时钟滴答走过千年的最后几秒钟。 8.clock, secondary, with only minute and...
Many GPS receivers provide a 'one pulse per second' (1PPS) output signal, and some receivers are optimised for timing applications. This paper examines the 1PPS output pulse of three inexpensive GPS receivers: Trimble Lassen LP, Motorola M12+ Oncore and Sigtec MG5001. The Trimble and ...
