PPS    One Pulse Per Second    

TRAIM    Time-Receiver Autonomous Integrity Monitoring algorithm (on clock and frequency) which automatically detects and rejects faulty satellites from the solution. TRAIM assures high PPS integrity.    

Self-Survey    The receiver enters automatic Self-Survey mode on power-up during a period of time (10 or 20 minutes depending on the receiver) to ensure accurate reference position for improved timing accuracy. When the self-survey is complete, the receiver outputs PPS with only one satellite being tracked.    

Optional:
TSS-P software for Windows platforms.
TSS (Time Service Software) updates PC clock with a guaranteed accuracy of 1(one) millisecond by using a GNSS receiver on a com port providing 1PPS and NMEA messages. The software includes specialized algorithms to guaranty the accuracy.    




Z250 GNSS RECEIVER WITH NTP SERVER & EXTENDED TEMPERATURE RANGE

  



COMPACT FULL METAL JACKET DESIGN

z250 has been designed around the Trimble® BD910 GNSS receiver module, originally for applications requiring high accuracy from multiple GNSS constellations in a very small enclosure . Mobile platforms can now embed proven Trimble RTK technology using a very compact enclosure 108.5 x 84 x 30mm form factor.

Designed and manufactured in France, the product is fully tested whatever is the final configuration. This design ensures the high quality GNSS signals are protected from the sources of EMI on the host platform. It also significantly reduces radiated emissions which speeds compliance certification and time to market.

MULTI CONSTELLATION GNSS

z250 supports the L1 frequency from the GPS, GLONASS, Galileo, and Compass constellations. An L1 RTK engine delivers 1–2 centimeter positions. For applications that do not require centimeter accuracy the Trimble integrated module, BD910, contains an advanced Kalman filter PVT engine that delivers high accuracy GNSS, DGNSS or SBAS positions in the most challenging environments such as urban canyons. Different configurations of the module are available from SBAS to multi-constellation L1 RTK. All features are password-upgradeable, allowing functionality to be upgraded as your requirements change. The receiver also supports Fault Detection and Exclusion (FDE) and Receiver Autonomous Integrity Monitoring (RAIM) for safety-critical applications.

DEMONSTRATED PERFORMANCE

Industry professionals trust Trimble embedded positioning technologies as the core of their precision applications. With the latest Trimble-precise Maxwell™ 6 technology, the Trimble BD910 provides assurance of long-term future proofing and trouble-free operation. Moving the industry forward, the Trimble BD910 redefines high-performance positioning:

On-board multipath mitigation,

Proven low-elevation tracking technology.

FLEXIBLE INTERFACING

z250 was designed for easy integration and rugged dependability. Customers benefit from the Ethernet connectivity available from RJ45 connection, allowing high speed data transfer and configuration via standard web browsers. USB and RS-232 are directly available from the enclosure. As the product interface directly the Trimble module BD910, all the easy to use software commands simplify integration and reduce development times.

HIGH PRECISION TIME SERVICE SOFTWARE FOR WINDOWS PLATFORMS

ZTI Communications offers High Precision Time Service Software (TSS) for Windows platforms ensuring one millisecond guaranteed accuracy: TSS-N for use with a NTP server, TSS-P for use with a GNSS device via a communication port.

 


TSS-N :: Time Service Software for Windows NTP Clients

Today the Network Time Protocol (NTP) is widely used around the world, to synchronize the computers and provide a very precise time reference. NTP protocol supports an accuracy of time down to nanoseconds but the real accuracy which can be achieved depends on the operating system and the network performance.

NTP relies on a reference clock to define the most accurate time and synchronizes all clocks on a network to that of the reference clock. NTP uses Coordinated Universal Time (UTC) as the universal standard for current time. UTC is independent of time zones and enables NTP to be used anywhere in the world regardless of the time zone settings.

An NTP time server is used to obtain the correct time from a time source and adjust the local time in each participating computer. The time source used by the time server is very important as this forms the basis of time updates across the whole network. Recent studies show that the use of Internet time servers is not recommended for industrial or commercial applications: there are high numbers of bad clocks, unbalanced nature of the network load, security reasons…

So it is essential to use an accurate auditable time source such as a GNSS (Global Navigation Satellite System) source or an atomic clock.

An NTP time server synchronized by GPS for time synchronization on a computer’s network is an ideal professional level solution. But what is the uncertainty for the synchronized computer? (1, 10 or up to 50 milliseconds when using a NTP client on Windows computers).
And what is the time accuracy and uncertainty delivered to the applications running on the synchronized computer?


Key Benefits

Ensures accurate time for applications running on Windows client machines

Delivers precise time with uncertainty associated to the applications through an API

Option to update or not Windows time

TSS-N = Windows service running continuously and nothing else to do (no manual synchronization or parameters to adjust)

Guaranteed accuracy of one millisecond for the PC running TSS-N thanks to the use of NTP and specific algorithms developed by ZTI Communications

No more PC clock drift

Application Examples


Metrology, alarms and logs time-stamping, network traffic measurement, time-stamping authority, time transfer measurements, e-business, high frequency trading, financial network measurement and more…

TSS-P :: Time Service Software for Windows Clients with a GNSS device (COM or USB port)

High Precision Time Service Software TSS-P provides accurate time synchronization and updates automatically the PC clock. The software needs using a GNSS device via a communication port (USB / RS232 / RS422) providing 1PPS signal (Pulse Per Second) and NMEA messages (GGA, GSA, GSV, RMC, VTG).

Synchronized to GPS/UTC with the 1PPS signal delivered by the GNSS device, TSS-P delivers a guaranteed accuracy of one millisecond thanks to sophisticated calculations and corrections algorithms developed by ZTI Communications.

The PC clock is updated by TSS-P if the computer is not set to automatically synchronize with an Internet time server.

Key Benefits

Ensures accurate time for applications running on the computer

TSS-P = Windows service running continuously and nothing else to do (no manual synchronization or parameters to adjust)

Guaranteed accuracy of one millisecond for the PC running TSS-P thanks to the use of specific algorithms developed by ZTI Communications

No more PC clock drift

Display: satellite information / geolocation information / UTC time and PC clock with the time zone / Last windows clock update / status (synchronized or not, synchronization in progress…)
