Argos-4 Data Collection System

Data collection and relay instrument flown on EOS-06 / Oceansat-3.

Sensor

Argos-4, also named the Advanced Data Collection System, is part of the Argos data collection and location system. The system collects and relays data from in-situ platforms equipped with sensors and transmitters through Argos instruments aboard polar-orbiting satellites, providing worldwide coverage and platform location.^[1]^[2]

The Argos-4 receiver operates at 401.65 MHz. Data collection platform bit rates are 400 bits per second in the basic mode and up to 4,800 bits per second.^[1]

The movement of a satellite carrying an Argos instrument enables the system to locate an in-situ platform using Doppler-shift calculations. Ground processing organizations process the data and deliver it to end users.^[2]
