I haven't had a chance to try it yet, but what if the GPS is on pedicabs, autorickshaws, speedboats and horse carts...
I have a GPS on my Pico!
It was a spontaneous expression after I managed to discover that the Axioo Pico said it was a global positioning software (GPS) with a trial version of Garmin on the shared Pico system, together with the device Sierra USBConnet Modem 881 .
GPS is the 'Global Positioning System', which is a satellite-based navigation system developed by the United States Department of Defense (DoD). GPS can provide a user's location anywhere on earth.
Positioning systems are widely used in Geographic Information Systems, Remote Sensing and Navigation applications. Every application has a protocol and every subprotocol.
To create this GPS system, it is divided into 3 segments, namely:
1. User segment
This segment includes users using GPS receivers. The GPS receiver itself consists of a number of different technologies and applications. This GPS receiver will calculate the location of a corner/person/whatever we are looking for and the accuracy is around 10m.
2. Spatial segment
Now this is the most important part, which is the part that consists of 24 satellites. The satellites are located at an altitude of 20200 km, the orbital altitude is at. And why is it so far? it is the correct distance if one calculates in mathematical terms, atmospheric perturbations and the range of the satellite area to the earth.
The previous GPS satellites (24) belong to the USA, if they belong to Russia they are called GLONASS (there are 24 satellites), and there is one called GALILEO (belongs to a European satellite). Apart from GPS, the other two sets of satellites are rarely (or not yet) used because they are quite difficult to operate and maintain.
3. Control segment
What is meant by "control segment" is the control station on the ground. And it serves to unite the positions of these satellites.
To access the GLOBAL POSITIONING SYSTEM, a GPS device is made in the form of a GPS chip. This chip set consists of sensors, position and data systems, and computation. GPS chips can be connected to other chips to form modules. The MC8781 module is the module officially incorporated into the Sierra Wireless AirCard 880/1U.
Each device has a different purpose and a different target market. Because of this, the technology incorporated in GPS devices is also different.
The various categories of GPS devices are divided into 5 categories, including:
In order for a GPS device to be read by other devices, an egress protocol is required. NMEA (National Marine Electronics Association) according to the standard protocol used. NMEA itself also has different writing formats (http://www.kh-gps.de/nmea-faq.htm). Likewise with other GPS output (receiver) protocol standards. Understanding these formats can help you build web servers that use GPS data and build GPS-based applications.
Almost all established software, especially new ones, can read the output in the standard GPS format (Open GIS Consortium for GPS Format).
Garmin Mobile PC itself is one of the support programs (to be used) for the Garmin brand GPS device (and other GPS receivers). Other supporting software is required to manage the Garmin Mobile PC Software: for example, to create maps, calibration, etc. IMG is also an image format released by ERDAS Imagine.
You can also buy the commercial version of the GPS receiver, which is about an inch and has very high accuracy + low power. Generally, the latest GPS technology is used by the military first, so if there is newer technology, a commercial version is released, as well as satellite imagery and more.
The Indonesian map user on Garmin is a map with a scale of 1:250,000, each level of the map has an aspect of generalization, so maps at this scale have a level of confidentiality that still requires questions. Unlike the original, curved lines can also be described as straight. To reduce the margin of error, you can use a map with a scale of 1:25,000.
On the Sierra USB Connect881U GPS modem, the error rate is 12-25m, but maps 1mm 1:25,000. Visually it does not look dry. However, on a 1:250,000 map, the difference will be noticeable due to the generalization aspect.
From my experience, there is a difference or variation in ground vehicle speed readings, with a vehicle speed reading of 90 km/h, the Garmin reads a moving speed of 84 km/h or a difference of 6 km/h hour. But for the speed below 60 km/gear the difference is not very noticeable.
If you are interested in using GPS on a laptop, you can now use the Sierra 881U modem as a GPS receiver. Follow the below method.

- First download the garmin software from the Garmin website. address
- Install Main.msi first, then click Setup.exe
- restart your computer
- Update Garmin Mobile PC to update version 5.00.50 which can be downloaded directly from the Garmin website. Link: http://www8.garmin.com/support/collection.jsp?product=010-00685-00.
- Restart your computer after you have completed the update process
- Follow the "unlock guide.txt" or "readme.txt" instructions to activate your Garmin mobile computer
- The GPS map of the Indonesian region can be downloaded from the navigation.net site at the link http://www.navigasi.net
- After you finish downloading [GMAv0.xx]navigasi.net.zip, use WinZip or WinRAR to extract the file GMAPSUPP.img (Insider looking for Garmin map source applications).
- Copy and paste the GMAPSUPP.img file into the GarminMobilePC installation directory. Example from C:\GarminMobilePC to D:\GarminMobilePC
- Then download and update the 3G version of Watcher to GPS. It can be downloaded directly from the Sierra Wireless site.
- After completing the 3G Watcher update, connect the Sierra 881U modem, click 3G Watcher. Press Tools > MP Physics Interface. Select the USB option.
- Press Tools > GPS Display for the built-in GPS monitor
- Press the Play icon in the center to start searching for satellites. Wait a moment. Proceed if it fails (Error), press the tick and then stop playback again to repeat the search process again. If successful, you will see the words "I have a fixed position on... (x satellites).
- After you have successfully received the satellites, turn on the Garmin mobile computer. The mobile computer will automatically connect the modem to the Sierra 881U.
- Finished. Please explore your city and never get lost again.
