Here are the most common TAIP messages used in GPS configurations on OMG and MG90 devices and can be configured in the GPS tab on the LCI for both local and remote forwarding:
​
​Altitude/Vertical Velocity – AL
Applicable AL message qualifiers: This message requires the reception of at least four satellites and reports the altitude relative to mean sea level (in meters) and the vertical velocity (in miles per hour).
​
​Compact Position solution – CP
Applicable CP message qualifiers: This message reports time, latitude, and longitude. The GPS time of day is the time of the fix rounded to the nearest second.
​
​Identification number – ID
Applicable ID message qualifiers: This message is used to report the identification number you assign to the unit, which consists of a unique combination of four alpha-numeric characters. If the ID string is shorter than four characters, the module prefixes the string with zeroes (0).
​
​Initial Position – IP
Applicable IP message qualifiers: This message helps to provide a reference position and altitude thereby decreasing the amount of time needed to locate the first fix.
​
​Long Navigation – LN
Applicable LN message qualifiers: This message reports the latitude/longitude/altitude, the horizontal and vertical speed, and heading. Unlike the Position/Velocity (PV) message, LN provides three-dimensional information. The LN message also reports the ID’s and IODE’s of up to eight satellites currently being tracked. The total length of the sentence varies based on the number of satellites (SVs) being used.
​
​Position/Velocity solution – PV
Applicable PV message qualifiers: This message queries and reports the latitude/longitude, speed, and heading. Unlike Long Navigation (LN), the PV message provides 2-dimensional information only. The Set qualifier is provided to allow more accurate initial position setting when doing a cold or warm start. This capability is rarely used.
​
​Reporting Mode – RM
Applicable RM message qualifiers: This message sets report control flags for configuring the protocol. Note that each element is optional so only those flags to be changed need to be included in the command. Each element is delimited with a semicolon.
​
​Status – ST
Applicable ST message qualifiers: The message queries and reports on the operational status of the GPS sensor. This message includes both numeric codes and bitmapped values.
​
​Time/date – TM
Applicable TM message qualifiers: TM reports the time of day and date as computed by the GPS sensor. The time is in UTC if the GPS UTC offset is available, or in GPS in the GPS UTC offset is not available.
