📳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.

1. Collect minimum 2 hours of observations at control point

2. 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:

  1. Pre-surveyed point

  2. 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
