“History” command index
The GPS satellites are continuously transmitting a radio message containing information,
including when the data was sent. When the GPS receiver fitted in the vehicle is
powered on, through the connected GPS antenna, it receives continuously the radio
messages sent from satellites containing GPS information the sent data. The received
information from at least 4 satellites will be computed and carried out the necessary
calculations to determine its current position. This data solution can be stored in the on-
board Flash memory for further evaluation.
The History functions enable the MAMBOII device to store the position and time into the
history storage space (a portion of FLASH which uses 960 Kbytes memory size). When
the MAMBOII unit has obtained
a
GPS Fix
, it is capable of saving up to 245.715 position
records in its history memory space. The History function works on what is called a FIFO
principal: First in, first out, it means when the memory space has been used up, the
oldest records will automatically be deleted to make space for new incoming data.

Command description
This command records a new GPS position entry (including current position, speed,
number of satellites and time) into the history memory space. Additional
information can be attached to each entry, if the
and
parameters
are defined. Entries can be written without having a valid GPS fix (i.e. store user
messages, IN/OUT states or other additional information).
Parameter Description
<
flag

It determines whether or not additional information has to be stored in the history
memory. Following are listed for additional information in hexadecimal value
