SNOE & BATSAT

A demonstration satellite for the Teledesic constellation, originally labeled Broadband Advanced Technologies Satellite ("BATSAT"), and later renamed "Teledesic T1." The satellite differed in size and design from the anticipated satellite for the final constellation, but was designed to support two-way communications at speeds up to E1 rates in the 28.6-to-29.1-GHz band.

The Student Nitric Oxide Explorer (SNOE), also known as Explorer 72 and STEDI 1, was a small scientific satellite which studied the concentration of nitric oxide in the thermosphere.
