Dialogue between satellite and transmitters
For more than 20 years, the Argos data collection and location system has been supplying information to close on 1,000 scientific organizations and customers in 69 countries.
Since the 1st Argos instrument was launched in 1978, the system has deployed a number of enhancements.
With the launch of the Argos-3 instrument end June, it is set to take another major step forward.
This new instrument will bring a downlink capability—previous generations only supported uplinking to satellites—to enable the satellite and transmitters to establish a real dialogue.
Via this downlink, users will be able to send instructions to transmitters and reconfigure their settings, increase transmitter life span and uplink more data on each satellite pass.
The new generation of instruments will afford better detection and location performance, and will increase capacity.
1st steps for Argos-3/Sarsat-3
At the Baikonur Cosmodrome in Kazakhstan, the satellite will now begin the launch preparation campaign, undergoing functional tests on all the instruments in readiness for launch end June.
In the meantime, users can look forward to improved services by year-end once the satellite has completed in-orbit commissioning.
* Argos-3 and Sarsat-3 were developed by Thales S.A. and Alcatel Alenia Space under oversight from CNES, which is prime contractor for both systems.
