GNSS and Environmental Protection

  • Code and Carrier Phase Measurements

  • Botany

  • Geomorphology

  • Geology

  • Applied Geophysics

  • Environmental Hydrology

  • Single Frequency Receiver (TRIMBLE)


G ns s and environmental protection1
GNSS and Environmental Protection

  • Single Frequency Receivers (TRIMBLE)

  • Code measurements

  • mapping for botany and geomorphology

  • Carrier phase measurements

  • special geomorphologic applications

  • for applied geophysics

  • env. hydrology and botany (study of snow patch)

  • Dual Frequency Receivers (Leica)

  • mass movements monitoring (ploughing blocks)

  • crustal blocks movements (permanent station on

  • Snezka Mt.)

Snow cover monitoring3
Snow Cover Monitoring

The snow depths maxima were 15.7 m, 6.1 m, 13.4 m,

7.6 m and 14.2 m recorded in five winter seasons

between 2000 and 2004

Single Frequency Receivers

(TRIMBLE Pro XR and Power)
