2. Principles and restrictions This methodology has been developed to track target group movements based on the following principles: 2 1. Difficult access to electricity for GPS recharge 2. Working on no GSM/GPRS coverage areas 3. Need of develop a methodology with low target group interaction with the device 3. INDEX 1. Device First Charge 2. First data acquisition 3. Software installation 4. Device Configuration 3 4. Device Configuration 5. Device delivery to target group (2 OPTIONS) 6. Recovery data 7. Roles and Tasks 4. Device first charge For the first time using the GPS unit, charge the battery until it is fully charged Why? 4 The battery comes virtually uncharged, having only enough battery for a few minutes worth How? Take the power cable and connect it to the GPS unit (mini USB plug) and recharge through USB cable 5. Device first charge 5 Charging 6. Device first charge When the Power LED is green, the battery is under charging mode When the Power LED is off, 6 When the Power LED is off, the battery is fully charged When the Power LED is Red, the battery is low. Please recharge. 7. First data acquisition Once the battery is fully charged: 1. Go to an outdoor environment 2. Separate the GPS from the main body 3. Switch on your GPS to LOG mode JUST when 7 using the first time 8. First data acquisition Why? 1. The GPS device is manufactured in another country so its necessary to calibrate the GPS in the destination country. 8 2. To start to acquire satellites position, GPS needs outdoor environments 3. The body of the target group can block part of the satellite coverage (see image previous slide) 4. LOG mode: Continuous data record. This mode records data when the device detects enough satellites (no schedule) 9. First data acquisition Switch on GPS unit GPS will start to acquire satellites data Once de GPS position is 9 This should only be done the first time you switch on the GPS First time of device connection it will take more time than usual Only Managers should make this operation with the GPS once All data recorded in this step is not useful and can be deleted Switch on GPS unit (LOG mode) satellites data Once de GPS position is fixed, orange LED will be flashing 10. Software installation Insert Software CD to your computer and select BT-TR Q10000 model 10 Press Next button until installation completed successfully Restart your computer Why? This Software is necessary 1. To configure GPS 2. To download and storage data 11. Device configuration Start Q-TRAVEL program and enter software product key 11 Product key is enclosed with the software CD Because it is the first time we connect this device, there are not tracks and data so we should press Cancel button 12. Device configuration Why? 1. To establish the sampling interval (positions every n seconds when the device is ON) 12 2. Schedule automatic GPS ON and OFF to acquire every day position measurements in time intervals, if neccesary 13. Device configuration Connect GPS to the computer (LOG or NAV mode) and open Q-Travel Select File menu and click on Config GPS 13 14. Device configuration 1. Select General mode 2. Log every 15 seconds Why? To assure the memory of device is not 14 To assure the memory of device is not full of data after 2 months of work (maximum storage capacity: 150.000 positions) 3. Turn on Buzzer Why? This parameter makes the device beep when it switches on (like an alarm). (Buzzer reminds the target group that the device is ON, but it is not mandatory to activate it if it is annoying) 15. Device configuration Schedule the GPS to acquire measures in different time intervals every day automatically Why? Select in Turn on log at the following time (periodic) area of the CONFIG form.. 15 Its necessary to switch to NAV mode 16. Device configuration 1. Select e. g. 3 schedules every day (Sun to Mon) 2. Time of measures (UTC time) Morning: e.g.07:55 to 08:10 How? Why? 16 Mid day: e.g.10:05 to 10:15 Evening: e.g.17:40 to 17:50 (data capture before sleep time) This interval it is recommended to be at least 10 to 15 min to reach good satellite coverage Why? The time of measures are just a recommendation. Managers should decide which are the best times of measures for the project . 17. Device delivery to target group 2 OPTIONS OPTION 1: Schedule the GPS to acquire n measures every day automatically (GPS device in NAV mode always) 17 OPTION 2: Ask the target group to acquire position every time they are in a new place (GPS device from OFF to LOG mode) Managers should decide which is the best option depending on target group capabilities 18. Device delivery to target group 2 OPTIONS OPTION 1: Schedule the GPS to acquire n measures every day automatically (GPS device in NAV mode always) 18 Very low target group interaction (less errors) Advantages Target group only have to charge the battery Battery life is less than the other option Disadvantages Device configuration must be done by the manager 19. Target group training OPTION 1: Schedule the GPS to acquire n measures every day automatically (GPS device in NAV mode always) Target group only have to charge the battery 19 Blue light should be flashing in sleeping mode Orange light should be flashing when capturing data Battery light red: Device has to be recharged Battery light green: Device battery is charging. When it is OFF, battery is charged 20. Device delivery to Target group 2 OPTIONS OPTION 2: Ask the target group to acquire position every time they are in a new place (GPS device from OFF to LOG mode) Advantages Disadvantages 20 This option will optimize the battery consumption Advantages The configuration of the device (schedules) is not necessary Target group have to switch the device from OFF to LOG mode Disadvantages Risky option if target group forget to switch back to OFF (battery will run out) No data will be recorder if the device is OFF 21. Target group training OPTION 2: Ask the target group to acquire position, every time they are in a new place (GPS device from OFF to LOG mode) Target group have to switch from OFF mode to LOG mode until orange light flashes and then switch it OFF 21 Orange light should be flashing when capturing data Battery light red: Device has to be recharged Battery light green: Device battery is charging. When it is OFF, battery is charged 22. DEVICE CHARGE Managers and teams working in field should provide the best option to charge the devices (same as those used for mobile phones) via USB cable 22 Solar Panels External Universal Battery Charger 23. Recovery data from devices 1. Connect via USB to a PC or laptop with Q-Travel installed 23 2. Switch the device in LOG or NAV mode (not OFF) 24. Recovery data from devices 3. Select Tools menu and click on Options 4. Separate tracks when waypoints time difference is more 24 4. Separate tracks when waypoints time difference is more than e.g 720 min Why? Every day has e.g. 720 minutes. This example will show us one track per day (its just a visualization of data recorded, not other implications) 25. Recovery data from devices 5. Click on Read Device Log and import all tracks 25 The software will read and import to the computer all data storage in the device 26. Recovery data from devices 6. Select Raw Data Manager to export and save all data 26 Why? This function exports all the positions acquired to an Excel file. 27. Recovery data from devices Data should be upload to a MapPrint Service (Argongra Product) to: Have a secure data storage Have a quick platform for data visualization Have a productive platform for data analysis 27 Have a productive platform for data analysis 28. Further proccesses 7. Once all the data has been imported and saved, device can be cleaned of data if it is going to be used again. 28 29.
