how DG-PRO1 works on Android™.

Location information of DG-PRO1 can be used with Android™ app that uses most GPS including Google Map.5

Power supply

DG-PRO1 does not have a built-in battery. External power supply such as mobile battery is required.
The external power supply support to a wide power supply voltage of 4.5 to 15.5V DC.

USB power supply

Standard 5V USB Type-A cable is included. Car USB connector, USB charger, mobil battery and so one can be used.(Depending on the mobile battery used as a power source, the output may be stopped because the DG-PRO1 consumes less current)

Mobile batteries recommend Anker PowerCore+ mini.

It is an image of mobile battery ANKER recommended by DG-PRO1.

Current consumption is about 70 mA in Bluetooth connection state. For 3000 mAh battery, it can be used for about 42 hours continuously.

Vibration-proof battery holder

Recommended mobile battery holder for Anker PowerCore+ mini. Prevents contact failure between the 5VUSB cable and the battery due to vibration. It enables stable power supply even with vibrations such as motor sports, bicycles and running.

It is a holder to protect SU002 and Anker PowerCore + mini

DC 4.5 to 15.5V power supply

Please use SA001-1 (12V cable) sold separately when using DC 12V such as automobiles and motorcycles. It can be connected not only to 12V but also to a DC 4.5 - 15.5V power supply.(Connection requires electricity knowledge and skill. Please have someone with expert knowledge.)

Sharing with data logger power supply

When using the data logger Drogger (SL001) for motor sports, you can also use a branch cable SW001 that can supply power to both SL001 and DG-PRO1 with one power supply. Both 5V USB cable or SA001-1 (12V cable) can be used for the power input side of this power supply branch cable.

How to use

Describes how to use the Drogger GPS for AndroidTM app.
Drogger GPS provides mock provider service for use with Google map and other GPS app via Bluetooth with DG-PRO1...
Use DG-PRO1 with AgriBus-NAVI
This time, I will explain how to use DG-PRO1 as AgriBus-NAVI GPS of agricultural info design, LTD. …

Let's improve the performance of the antenna

The accuracy of the GPS is largely affected by the sensitivity of the antenna. Sensitivity varies depending on the possession method and the installation position. Here are tips on improving sensitivity.

Separate the antenna from the metal by 3 ~ 5 cm

The characteristic of the built-in antenna is that the sensitivity drops when the object which passes electricity such as metal or carbon is within 3 to 5 cm. Even if there is moisture, such as the human body, open a gap.

The goodness and badness of the sensitivity can be confirmed with Satellite sensitivity graph of Drogger-GPS app. The longer the graph, the better the sensitivity. As you get close to the metal plate and so on, you can see immediately that the whole graph becomes short. The picture below is a comparison between the case where the metal plate is laid down on the dashboard of the car and the case where it is not.

DG-PRO1 and metal and carbon are used separately.

It can be understood from the length of the graph that the sensitivity is better if there is no metal around.

Find the best position

When installing on a car, motorcycle, bicycle, and so on, look at the graph of the app as shown in the photo below and find the place where the graph is the longest. When using the mounting stay, use resin instead of metal or carbon.

DG-PRO1 and metal and carbon are used separately.

In the case of this car, the top of the windshield was the best place with the longest graph.

Make Main body vertical

Normally the GPS antenna is placed horizontally on the ground, but for DG-PRO1 let's stand vertically so that the cable side is down. Antenna is on top and sensitivity improves.

DG-PRO1 is used vertically.

Let's protect cables with strap holes

Please use the strap hole when attaching the main body. If you use cables instead of straps, there is a danger of damage due to vibration and so on.

Recommended mobile battery

USB mobile battery is the easiest power source for DG-PRO1. However, depending on the mobile battery, the current consumption of the DG-PRO1 is too small and the power supply is stopped. If you already have a battery, please make sure that it works continuously for about 5 minutes.

When preparing from now, we recommend Anker PowerCore + mini


Stable power supply with vibration-proof battery holder

In motor sports, bicycles, runnning, and other situations with many vibrations, let's use Vibration-proof battery holder and Anker PowerCore mini. Preventing contact failure due to vibration of 5V USB cable and battery, stable power supply is possible even with severe vibration.
