Telemetry limitations<br />
�� Analog readings are 6-bit 6 bit only: 64 discrete levels<br />
means very low amplitude resolution<br />
�� At the lowest data rate, a given parameter<br />
appears in the stream only once every 51.2<br />
minutes<br />
�� Late in the mission, many readings are outside<br />
calibrated range, some nonsensical<br />
�� Aging sensors may not be reliable<br />
�� When Vbus bus < 28 V, V,<br />
readings are questionable<br />
