| Research Abstract |
It is well-known that forest canopy adversely affects GPS positional accuracy. We introduced an extendable GPS antenna pole to GPS measurements under forest canopy. We used dual-frequency GPS receivers for data collection while changing the GPS antenna height at 2, 5, 8 and 11m. The results for the L1 code solution clearly showed that the positional accuracy was enhanced by raising the GPS antenna to a higher position. We also conducted GPS measurements using the MTSAT, we could not receive GPS signals from the MTSAT in the closed canopy environment. In the open sky environment, we could receive GPS signals from the MTSAT, but the rate of reception was 59.4%.
