English NMEA Data Output Introduction MobileMapper CX can output an NMEA message on its physical and virtual ports (COM1, USB serial and COM2). The content of the NMEA message is user-defined. Defining the NMEA Message - Tap , then Programs>GPS Utilities>GPS Ports Configuration. - Tap on the NMEA tab. - Check on all the NMEA data strings you want to include in the output message and for each of those strings, choose an output rate in seconds.
The USB port must be configured to emulate a serial port. Follow the instructions in Setting the Mini-USB Port (I/O Module) on page 5 to do this. Then: - Tap , then Programs>GPS Utilities>GPS Ports Configuration. - In the GPS Auxiliary Output pane, check on the Enable Messages option and then select “COM6” in the Port field. - Tap Configure Port to configure the selected port. Enter its baud rate, number of start and stop bits and set its parity and flow control parameters. - Tap OK.
English Optimizing Accuracy General Guidelines There are five basic rules for recording MobileMapper CX rover data so as to achieve the optimal accuracy: 1. Allow the receiver to have full “view” of the sky the entire time a job is open, not just when logging data to a feature. There are three things you can do to improve signal reception: • While you do not need a survey-grade external antenna for sub-meter accuracy, using one will yield better accuracy in all environments.
There is one additional rule for optimizing MobileMapper CX accuracy when recording rover data that will be differentially corrected by MobileMapper Office in post-processed mode: All features must be logged while the receiver is continuously tracking at least 5 satellites with a PDOP less than 4 for at least 20 minutes. You need to record only a single “epoch” of GPS data to get a position, but you need to record at least 20 minutes of data to post-process it for sub-meter accuracy.
English If the period of continuous lock is less than 5 minutes, the SBAS-corrected position may be more accurate. When recording a job for post-processing, the receiver records GPS measurements the entire time the job is open – not just when you’re recording data into a feature. Therefore, you do not need to record each feature for more than 20 minutes. Each feature has to be recorded during a portion of the job file where you maintained lock on the satellites for at least 20 minutes.
Updating MobileMapper CX OS Firmware The current version of MobileMapper CX Operating System (OS) firmware can be downloaded from ftp.magellangps.com in the /Mobile Mapping/MM CX/Firmware/OS/ folder. 1. Turn on MobileMapper CX and either attach it to external power or make sure that there is at least a 25% charge in the battery (tap Start>Settings>Control Panel>Power). 2. Copy the OS firmware file with the *.nbx file extension (e.g., NK_x_xx.nbx) to an SD card.
English 8. When you see a message saying, “Operating system updated successfully,” tap OK on the OS Loader window. 9. Tap in the upper right of the Windows screen to exit back to the desktop. 10.Turn off the receiver by tapping , then Shut Down and then the OK button. 11.After a few seconds, MobileMapper CX’s green LED will shut off. You may then press the power button to turn the receiver back on. 12.
>Shut Down and tapping OK. 13.Once MobileMapper CX’s power light goes off, restart it, tap >Settings>Control Panel and scroll down to the Magellan System Info icon. 14.Double-tap the Magellan System Info icon and confirm that the GPS F/W version is that which you just uploaded. 15.To update another MobileMapper CX receiver with the latest GPS firmware, remove the SD card and insert it into the other receiver. Repeat Steps 6 through 14. 71 English 4.
English About Almanac Files When first using your MobileMapper CX, and because there is no recent almanac file available yet in the unit, the internal GPS receiver (or Mission Planning if used at that time) will use a default almanac file stored in its protected memory. After receiving GPS satellites for about 12 to 25 minutes, the internal GPS receiver will be able to create a new almanac file. This file will be stored in the “Windows” folder and named as follows: almyy.
English Assessing MobileMapper Beacon Reception Quality As long as the green lock indicator light on MobileMapper Beacon stays on, you can be certain that MobileMapper CX can readily deliver a DGPS solution using the incoming correction data packets from MobileMapper Beacon. You can verify this by running the GPS Status utility (see Viewing Current GPS Status on page 15; In the status bar at the bottom of the screen, “Differential GPS” should be displayed and the indicator light should flash in blue.
English The table below gives indications on how safe DGPS operation with MobileMapper Beacon will be, depending on the value of the SNR. SNR SNR<10 dB 10 20 dB DGPS Data Reception Quality Very Critical; DGPS mode steadiness is very unlikely. Good but critical; if signal deteriorates, even slightly, MobileMapper CX won’t be able to maintain DGPS mode. Excellent; there is signal level “in reserve”, which means even if the signal slightly deteriorates, DGPS mode will be maintained.
