Anyone who has studied geography knows that the current international standard time is called Universal Time Coordinated (UTC), also known as "Universal Standard Time". It is a combination of atomic time and UTC, based on the length of the second in atomic time, and as close as possible to UTC in moments. The most commonly used timing method in modern times is satellite timing, and it is widely used in the fields of car navigation, vehicle monitoring, traffic scheduling, shipping, communication base stations, and power and financial timing. For you to reveal the depth of the GNSS is how to realize the function of timing.

Satellite timing and GNSS timing module

The three core capabilities of GNSS, usually abbreviated as PVT, are Position, Velocity and Time.GNSS Timing Service: On every GNSS satellite, there is an atomic clock. This allows for precise time data to be included in the transmitted satellite signals. These signals can be decoded by means of special receivers or GNSS timing modules, which allow rapid time synchronization of devices with the atomic clocks.

GNSS satellite timing has clear technical advantages - higher timing accuracy and wider coverage.

Higher timing accuracy: Take BeiDou as an example. The time of BeiDou satellite navigation system is called BDT, which is atomic time and can be traced back to the Coordinated Universal Time (UTC) of China's National Timing Center, and the accuracy of the time difference control with UTC is less than 100ns; JUNODA's existing GPS timing module and BeiDou timing module can reach the timing accuracy of 10nS, 15nS and 20nS.

Wider coverage: thanks to the signal coverage of GNSS satellite, in the weak signal or no network coverage in the mountains and jungles and other environments, especially for ocean navigation and aerospace scenarios, GNSS satellite timing can ignore the limitations of the physical propagation distance, the real-time output time data for GNSS timing module decoding and rapid time synchronization of the device with the atomic clock.

 GNSS Timing Module

For the applications of base station, electric power, communication, car navigation, vehicle monitoring, traffic scheduling, shipping, etc., JUNODA joins hands with MTK, UBLOX, and UW to launch a variety of high-quality and high-performance GNSS timing modules, which support three timing modes of BDS, GPS, and joint, and at the same time, they have the functions of positioning and fixing speed, and have the function of short-time time-keeping; they have the functions of <10ns, standard deviation 4.5ns, <15ns, <20ns, <15ns, <20ns, <20ns, <15ns, <20ns, <15ns, <15ns, <20ns. 15ns, standard deviation 4.5ns, <20ns, <30ns and other different timing accuracy of GPS timing module, BeiDou timing module; with a single-star timing function, when there is only one visible satellite, can still maintain accurate and stable time output.

Existing GNSS timing modules are highly integrated, compact, stable, low cost, excellent overall price/performance ratio, enhanced sensitivity and parallel dual-star reception to extend the coverage and provide integrity to cope with poor signal environment.GNSS timing modules are available with EASY, EPO and other auxiliary functions, which can also provide excellent positioning and timing performance under weak signal. Suitable for large-scale applications in the field of timing, the technology has reached the international advanced level.

Main features of GNSS timing module:

Receive GPS/BDS satellite signals in L1 frequency band and L1+L5 frequency band, and synchronize to generate high-precision timing signals independently;

Time delay automatic compensation, automatic measurement synchronization;

Can tame the local crystal to generate a clock signal with 10MHz stability;

Autonomous timekeeping: when there is no synchronization signal input, the GPS/Beidou timing module keeps time autonomously;

Support customization, various input and output time and frequency signals are optional;

Serial time information output.
