Park Manager

Role

The Park Manager module orchestrates the complete opening and closing of the observatory: opening the dome shutter, unparking the mount, starting tracking — and in reverse order for closing. It can operate in manual mode (one-shot action) or in automatic mode driven by time and weather rules.

Required devices

Parameters

Weather rules

Time rules

These rules define the opening window in Automate mode. They are mutually exclusive.

Sequences

Opening sequence

1. Weather check (if Must be OK rule is active)
2. Open dome shutter
3. Wait for shutter open confirmation
4. Unpark mount
5. Wait for unpark confirmation
6. Start sidereal tracking
7. Enter monitoring state (Open Monitoring)

Closing sequence

1. Stop sidereal tracking
2. Send mount to home position
3. Wait for home position reached
4. Park mount
5. Wait for park confirmation
6. Close dome shutter
7. Wait for shutter closed confirmation

Emergency stop

The Abort action simultaneously sends a stop command to the mount (TELESCOPE_ABORT_MOTION) and to the dome (DOME_ABORT_MOTION), then returns to Idle mode.

Automatic mode

In Automate mode, the module evaluates every 2 seconds whether the observatory should be open or closed according to the configured time and weather rules.
