Simulators

Whether the spacecraft survives eclipse: array sizing, battery depth of discharge and duty cycle until the orbit-average energy balance closes.

Used in Electrical Power Subsystem: Sandbox: size a power system →

Whether the passes are long enough: bytes generated per orbit against bytes actually downlinked at the chosen rate.

Used in On-Board Computer and Data Handling: Sandbox: data budget →

Whether the radio link closes: EIRP, free-space path loss, G/T, C/N0 and the margin left at ten degrees elevation.

How long a LoRa frame occupies the channel at each spreading factor, and whether the 1% duty-cycle rule still allows the traffic you planned.

Used in LoRa for Satellite IoT: Sandbox: airtime and link trade →

What a raw telemetry frame actually says: sync word, CRC-16/X.25 integrity and every field decoded byte by byte.

How high the airframe goes and how hard it comes back: burn, coast to apogee, stability margin and descent rate under canopy.

Used in Flight Computer Firmware: Sandbox: predict the flight you are about to log →

Whether a whole spacecraft closes: assemble one from AfriOrbit's real boards, fly it through eclipse cycles and ground station passes, and see mass, charge and downlink budgets settle or fail together.

What is actually on the flight hardware: the real KiCad layouts, every footprint, net and BOM line, read straight out of the board files.

Where the spacecraft will be and when you can talk to it: ground tracks, J2 drift, eclipse, pass prediction, Doppler and Walker constellations, from elements or a pasted TLE.

What the flight article looks like and how it is oriented: the EduSat CAD in three dimensions, lit by the real Sun vector and driven by the attitude law you pick.
