APPENDIX
We show you one of the results of position-fixing measured by our prototype Receiver in Nishinomiya, Japan 5:00 to 10:00 on May 4, 1999. This is the fixed point measurement. During this period, FAA carried out the flight experiment in Singapore, then our Receiver could receive correction data for many GPS satellites from POR. However, neither the TYPE10 message nor the ionospheric correction data around Japan were broadcasted at that time. As a result of this, our Receiver chose NPA position-fixing during this test.
In Figure 3 below, the radius of the outer circle is 80 m and the radius of the smallest circle is 20 m.
