The Scheduler for the Modern Era
Every pass, on one schedule.
Star-Sync takes contact and RF time requests, finds when each satellite is visible from each station, and books the passes on one shared schedule.
| Station / satellite | AOS | LOS |
|---|---|---|
| Inuvik NorthWest | ||
| SCISAT 1 | 14:04 | 14:15 |
| NEOSSAT | 14:44 | 14:55 |
| SCISAT 1 | 15:08 | 15:19 |
| Prince Albert | ||
| SCISAT 1 | 14:15 | 14:26 |
| NEOSSAT | 15:36 | 15:47 |
| Exclusion | 14:58 | 15:06 |
| Gatineau Quebec | ||
| SCISAT 1 | 14:25 | 14:36 |

01 — Functions
What the system does
- 01
Contact requests
Book a specific pass at a station. Pick it from the passes Star-Sync computes; AOS, LOS, RF on and off, and the orbit number are filled in.
/requests - 02
RF time requests
Request uplink, downlink and science time within a start and end window, with a minimum number of passes.
/requests - 03
Schedule
Requests become bookings on a ground station. The timeline shows bookings by station or satellite, the passes behind them, excluded time, and requests that could not be placed, from ten minutes to two weeks.
/schedule - 04
Satellites
Maintain each satellite’s name, TLE, priority, and uplink, telemetry and science rates.
/satellites - 05
Ground stations
Maintain each station’s latitude, longitude, height, mask angle, and uplink, downlink and science rates.
/stations - 06
Exclusion cones
Set a limiting angle between two satellites at a station. Times when they are closer than that angle are excluded.
/exclusion-cones - 07
Overview
See the next contacts, how much time each station is booked for, and which requests were not scheduled and why.

02 — Workflow
From request to booking
- 01
Request
An operator submits a contact request or an RF time request for a satellite.
- 02
Schedule
Star-Sync works out when the satellite is visible from each station, removes excluded times, and books the request.
- 03
Review
The booking appears on the schedule under its ground station. A request that could not be placed is listed with the reason.
