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 the point later through post-processing
• Adjust previously acquired coordinates
  • Use RoboDot Utility with Image Offset Tool

Post-Processing Workflow — OPUS

Use static post-processing to establish a control point before or after field work. OPUS uses reference-station data; it is not a PPP service. Check NOAA’s OPUS requirements and review the returned quality report.

1. Collect at least 2 hours of stationary observations for OPUS Static
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
