Operating Modes
Static Observation Mode
Primary function for establishing accurate survey points. Two workflow options:
Pre-Survey Workflow
- Secure point before additional operations
- Use for drone mapping/rover shot baselines
Post-Survey Workflow
- Begin operations immediately
- Determine point later via PPP
- Adjust previously acquired coordinates
- Use RoboDot Utility with Image Offset Tool
Post-Processing Workflow - Precise Point Positioning (PPP)
When collecting GCPs or surveying a point ahead of rover operations.
- Collect minimum 2 hours of observations at control point
- Submit rinex file *_opus.o to NOAA's OPUS with:
- Antenna type: NONE
- Height: Pole height + 0.094m to get the ground elevation
Base Station Mode
RoboDot provides Real-Time Kinematic (RTK) positioning in two accuracy types:
Relative Positioning
- High accuracy relative to base station
- Suited for local survey work
- Does not require absolute coordinates
Absolute Positioning
- Requires known point coordinates
- Reference options:
- Pre-surveyed point
- Real-time corrections from:
- Another positioned RoboDot
- Virtual Reference Station (VRS)
Rover Mode
Applications include:
- Ground control point marking
- Check shots
- Point surveying
- Geographical Information Systems
Repeater Mode
Considerations
- Terrain and obstructions that may reduce effective range
- Testing range before critical operations is recommended
Applications include:
- Large area mapping
- Operations with line-of-sight limitations
- Operations that require multiple simultaneous rovers from a single source
- Drone mapping while collecting GCPs
