Demand for using GPS receivers in the forest has been growing higher recently. However, effective use of GPS in the forest subjects to a few issues, namely (1) influence of topography on sky openness, (2) degradation of GPS signal by trees, and (3) handiness of GPS receiver in the forest. With the forthcoming GNSS and RNSS, and available GPS satellite forecasting, the influence of the topography should be reduced to some extent. Comparison of Bluetooth GPS receiver carrying highly sensitive SiRFstar III GPS chipset and conventional GPS receiver was carried out in the forest. It was found that highly sensitive GPS receiver is able to reduce GPS signal degradation problem significantly. Besides, cableless Bluetooth GPS receiver can be very handy for the use in the forest. So, even at the present moment, GPS is practical tool in the forest.
