AetherTelemetry is a company that manages environmental monitoring micro-satellites in low Earth orbit. Each satellite runs an onboard telemetry system that interfaces with various sensors, attitude controllers, and transmitters. The system stores and transmits the following telemetry parameters:
| Data stored | Variable identifier | Example data |
|---|---|---|
| The satellite's unique registration code | RegistryTag | SAT-942X |
| The name of the primary ground control station | StationName | Kourou-4 |
| Whether the main telemetry transmitter is currently broadcasting | TransmitterActive | True |
| The altitude of the satellite in kilometers | AltitudeKM | 35786.4 |
| The number of solar flares detected during the current orbit | FlaresDetected | 4 |
| A single-character flag for the orbital path sector | SectorCode | G |
Identify the most appropriate data type for each variable below by selecting one option in each row.
| Variable | Boolean | Char | String | Integer | Real |
|---|---|---|---|---|---|
| StationName | |||||
| TransmitterActive | |||||
