Introduction

Creating a GPS GSM Network Rover Profile

This guide describes how to create a GPS GSM network rover profile for your Pentax SMT888-3G Rev 2 GNSS receiver.

Although this guide describes using a SMT888-3G Rev 2 GPS receiver, the procedure in this guide can also be followed for connecting to other Pentax receivers such as the SMT888-3G and

G3100-R1.

Important Note

: You only need to create a particular profile once.

After that Pentax FieldGenius will preserve and use this alreadycreated profile. You are also welcome to create more profiles such as for a UHF radio GPS profile, but in this guide we explain how to create a GSM Network GPS profile.

Current

Version

This guide was written using Pentax FieldGenius Version 5.0.6.2 installed on a Getac PS236 with Windows Mobile 6.1 installed. If you are using a different version, your screens may look differently than what is displayed in this guide.

Before you begin

Have your Pentax SMT888-3G Rev 2, data collector with Pentax

FieldGenius installed, and a SIM card close by. You will need them to complete this guide.

Correct

Antenna

It is wise to ensure that you have the correct antenna height entered and proper antenna model selected before measuring with GPS.

Step

Action

In the MapView screen:

In this example we will enter a height of 2 metres since we are using a fixed 2-metre pole.



Tap on the Instrument

Display

Settings button.

This takes us to the Instrument

Settings screen.

In the Instrument Settings screen:



Tap on the Antenna Height button.

This takes us to the Antenna Height dialog.

continued

Step

Action

In the Antenna Height dialog:

Notice in the Model field you have three choices SMT888-3G (1),

SMT888-3G (2), and User Defined.

In this example we selected

SMT888-3G (1) because we intend on mounting our SMT888-3G to a rover pole.

How did I know that SMT888-3G

(1) is for the pole?

If you look at the Measure Point field the text informs us that we are measuring to the bottom of the antenna mount so that must mean we are using a rover pole. If this field said Bottom of grey cap then we would know that this is for a tripod setup (i.e. for the reference).



Select the antenna you wish to use in the Model field.



Enter the height of instrument in the Measured

Height field. In this example we are using a fixed

2-metre pole.



Press the Close button when finished.

You are now taken to the MapView screen.

Congratulations

You have successfully created a Pentax GPS GSM rover profile.

You then made a connection to your GPS receiver via Bluetooth.

From there you connected to your GPS network correction provider and started receiving network data.

You then entered the correct antenna height and selected the correct antenna model and are ready to start measuring.

Remember

, Pentax FieldGenius will preserve these settings in your instrument profile. You only have to create this profile once. In other words, you don’t have to follow these steps each and every time you want to survey using the GPS receiver and the Internet.

This guide will work with SMT888-3G and G3100-R1 receivers too.
