All the equipment needed for the remote telemetry unit (figure
5) is in a rugged black Pelican briefcase. The system consists
of a satellite modem, two batteries and a charger for backup
power, a satellite antenna, power cable, and a serial cable for
communications between the satellite modem and the DataRAM.

Telemetry Equipment
The remote satellite telemetry system uses a low-orbit satellite
system to send data from the DataRAM to a base station where
the information can be viewed and retrieved on the Internet.
The system sends 5-minute average mass concentrations
hourly by satellite to the Web site where the data will be posted
for
up-to-date, easy access. The data can be copied from the
Internet site into a database or spreadsheet application for
analysis.
