Some of our recent activities for GNSS Survey Work

Static Survey Mode:

• Observation method: Static method.
•  Observation time: 2h at least.
• Interval of data acquisition: 15 seconds.
•  Satellites received status: 5 up (more than 5 satellites)
• Horizontal: ± 05mm + 5ppm base line.
• Vertical: ± 10mm + 10ppm base line.
• Elevation Mask: Equal or greater than 15 degrees.
• RTK Survey:
  Field technique: Real- time Kinematic L1/L2
• Hardware required: L1/L2 Receiver. L1/L2 Antenna
• Time of Occupation: 3-5 Seconds per occupation
• Baseline Precision: 1cm+2ppm x Baseline Length
  (horizontal)\
• 2cm+2ppm x Baseline Length (vertical)
•  Advantages: Very short occupations, extremely efficient data
• collection, initialization done in the field (after lock is lost, reinitialization
• takes place automatically while moving-called OTF), can perform staking
• Disadvantages: For short baselines only (+/- 10 km)
