2 | Regarding the size of each: you can say how many floating point numbers each are. | Each float (single) number is 4 byte. Each byte is 8 bit. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||
3 | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||
4 | Inclusion in telemetry frequency can be different from logging frequency. For example, you can log a thermistor number on the satelite every 10 seconds, but only send one of the numbers every 100 seconds to the ground. So one number among those is chosen and sent to ground. This number can be a statistical result of all the numbers, for example the average. | If your measurement has a timestamp associated with it, you should specify | ||||||||||||||||||||||||||||||||||||||||||||||||||||||
