GNSS FREQUENCY & TIME REF, IRIGBxxx GENERATION & DISTRIBUTION, NTP & PTP SERVERS
GPS spoofing concern
Today concerns arise around GPS spoofing capability which mean building a system that creates signals that would appear to a receiver to be from GPS satellites. Transmitting these false GPS signals to receivers may cause them to lock onto the Lire plus …
IRIGB optical fiber distribution – TMO3000-T/R
Timelink is pleased to introduce its new optical fiber time transport system. TMO3000-T/R is a transmitter/receiver system made of 2 units allowing transmission of 3 analogs and 4 digitals signal over an optical fiber Signals are digitalized at the input Lire plus …
Spectre and Meltdown Vulnerabilities
Timelink products are protected against those vulnerabilities by the fact that in order to exploit the vulnerability, malware is required to be run locally within the system. When using a Timelink product, only authorized users with the appropriate password can Lire plus …
NTP basic – how it works
NTP is a protocol which allows a customer to be synchronized starting from a TCP/IP network.It was developed to provide a UTC (Universal Time Co-ordinated) of a precision about the millisecond for LAN network and about 50 milliseconds for WAN. Lire plus …
Disciplined clock – Stability and Time Error
When using a disciplined clock (GNSS disciplined for instance), two modes of operation are of importance. Disciplined Mode When the pilot is disciplined, the quality of the algorithm used and the pilot stability characteristics will determine the overall clock stability Lire plus …
Multi-source synchronized (GNSS, IRIG-B), configurable 8 outputs (IRIG-B, PPS, Digital, 10Mhz) Time and Frequency generator TMG5020
The TMG5020 time and frequency generator is a highly configurable equipment synchronized via GNSS or IRIG-B. It features 8 individually configurable outputs amongst IRIG-B, PPS, Digital pulse and analog 10Mhz. The TMG5020 can synchronize on a choice of time Lire plus …

The IRIGB standard
Communication systems, data handling systems, tracking and telemetry systems require time-of-the day information for data correlation with time. Parallel and serial formatted time codes are used to efficiently interface the timing system to the user system. Parallel time codes are Lire plus …
Transcodeur de code temps paramétrable IRIGB vers RS232/422
Le transcodeur SR1118 assure le transcodage d’un code horaire analogique IRIG B et produit une trame horaire RS232/RS422 ainsi qu’un signal 1PPS . Les codes de temps sont basés sur une porteuse sinusoïdale de fréquence 1 KHz modulée en amplitude Lire plus …
New PXI synchronization board
The TMC2100 IRIGB timing and control module synchronizes PXI systems using GNSS data to perform synchronous events. It features an onboard TCXO that can be disciplined to the GNSS with accuracy better than ±500 ns for long term stability. Lire plus …
