First examine the counit (= coordinate unit) keyword; in the example above it's 2, which means that navigation data are stored as arch seconds. To convert to desimal degrees, the scalco value is needed; here it's -100, which means that coordinate values should be divided by 100.
E.g., the sx (source X-coordinate = Longitude) has minimum value 1965730. This values can be converted into decimal degrees. • MTK • 66 parallel searching, 22 tracking channels • Receiver: L1, 1575.42 MHz • C/A code: 1.023 MHz • Update rate: 1Hz. • Antenna type: Built in patch antenna • Minimum Signal tracked: -165dBm • Dimension: 64.5 x 42 X 17.8 mm.
• Manufacturer: • Model BU-353 is obsolete - no longer in production. • Replaced by updated model; its specifications state: 'Accuracy -> Position Horizontal. DIFFERENTIAL GNSS RECEIVER CORRECTION DATA It is most practical to use GNSS ('Global Navigation Satellite System') correction services provided by the Norwegian Mapping Authority. Their correction signals are received through internet connection.
A roving GNSS receiver can then use GSM (or GPRS) mobile broadband. The receiver must also feed NMEA GGA-telegrams back, so the system can determine which of the fixed reference stations in the national network is most appropriate to base correction data on. Many GNSS receivers have serial data RS232C interface.
The serial port that is designated to receive correction data, can often also emit the required NMEA GGA telegram, thus only a single serial port must be interfaced to the internet. The Norwegian Mapping Authority provides two types of GNSS correction services.
Step # Description Screenshot 1 On client Windows PC, click on lower left magnifying glass. Enter 'software' in search field 2 Select 'Software Center' program that appears 3 Scroll down to Python and install. Select Python version 2.7.x 4 Open terminal window and confirm that Python is installed on your computer. By convention, Python 2.7.x will be installed in local directory: c: Python27. Since there is no PATH to that folder (unless you set environment variable), you have to specify the complete path to Python, when you want to invoke it.
5 If Python works fine, you should see similar display as screen shot to the right. Exit by typing exit(). 6 Now make a new working directory for processing nav data, and download raw data files and Python script (ref next section). In this example, folder is: O: www Edgetech-Chirp-Sonar DATA 2017 2017-July-Haflidi nav-data-processing 7 Execute Python script - and redirect output to file called 'test.txt' using command: c: Python27 python.exe Chirp-navdata-2017-processing-no-1.py > test.txt.

OK, my friend also bought the brand new Asteroid but his GPS also died within 1 week! WHAT A CRAP USB GPS PARROT!!!:mad::mad: I love the Unit it is getting better everytime, but again shows me how crap the GPS unit is.
My friend already ordered the GlobalSat BU-353S4 USB GPS Receiver SiRF Star IV which is much better than the orginal unit. So Parrot, maybe its time te get rid of the distributor of the UPS GPS and get some decent GlobalSat BU-353S4 USB GPS Receiver SiRF Star IV UPS GPS reveivers. Since the new version 2.1.2. My USB GPS unit is beeing recognised. Instead of UNKNOWN it displays a long sentence.
So maybe Parrot already ordered? Well rooting is very simple. Just google and you will find it. If you dont know what you are doing it is not a good idea to try it. But I guess there is always a nerd in your family/friends/neighbour that knows Android. I rooted my Asteroid and installed Google play and installed a lot of programs.
