Number of satellites in fix

9 DOP of fix
10 Height of Antenna Phase Center (see Note below)
11 M: height is measured in meters
12 The checksum data, always begins with *

Note – The PTNL,PJK message is longer than the NMEA-0183 standard of 80 characters.

Note – If a user-defined geoid model, or an inclined plane is loaded into the receiver, then the NMEA PJK string will always report the orthometric height (the field starts with the letters GHT). If the latitude/longitude of the receiver is outside the user-defined geoid model bounds, then the height is shown as ellipsoidal height (the field starts with the letters EHT).

Note – If the receiver does not have an application file, this string returns nothing in fields 3, 4, 5, 6, or 10.
