6.6 How to convert the coordinates
In order to convert coordinates from degrees, minutes, seconds format to decimal
format, use this easy formula:
d (minutes/60) + (seconds/3600)
Min. coordinates would be calculated as:
For example:
•
Longitude (min) = 10°53’11” E
• Latitude (min) = 50°40’16” N
Longitude (min)
X° Y' Z'' = [10 + (53/60) + (11/3600)] = 10.8863 // Longitude (min)
X° No conversion required
Latitude (min)
X° Y' Z'' = [50 + (40/60) + (16/3600)] = 50.6711 // Latitude (min )
X° No conversion required
Max. coordinates would be calculated as:
For example:
•
Longitude (max) = 10°57’17” E
•
Latitude (max) = 50°42’41” N
Longitude (max)
X° Y' Z'' = [10 + (57/60) + (17/3600)] = 10.9547 // Longitude (max)
X° No conversion required
Latitude (max)
X° Y' Z'' = [50 + (42/60) + (41/3600)] = 50.7113 // Latitude (max)
X° No conversion required
6.7 Explanation of the History Binary Data
Stored GPS history data into the history space memory can be retrieved either locally
(via serial link) or remotely (via a data or TCP connection). Whereby an executable
command, see chapters
3.2.4.2.5, page 92 has to be sent to the MAMBOII device if
such connection are available. Once, the MAMBOII receives such a command, it starts
to transfer the history selected data to the receiving device.
The history data is subdivided in packets, which are constructed in a specific binary
format to make possible low-cost solutions where data is downloaded via a TCP or GSM
connection.
For more detailed information about the history data conversion, see the Application
Note
“AppNotes_Transform_history_data.pdf”
