Scheduled for release in February, 2006, the ST-20 Argos PTT is compatible with our CR1000 and CR3000 dataloggers. Because Argos satellites are polar-orbiting, Argos field sites are well suited to deployment in high latitudes. The number of bits for each data point is user selectable. The ST-20 has low power drain, -40º to +70º C operating temperature range, and seven data buffers.
