Surveytogo Studio Android Device And

This tutorial will introduce you to the basics of GPS functionality on your android device and how SurveyToGo utilizes that location information to allow the Geo-Tagging of interviews as well as indicate geographical locations during an interview.

It can utilize a GPS receiver if available on the device, WiFi positioning if available and wireless (cell) positioning when available.

What will the Android OS will utilize on a specific device depends on the location services definition of the device and if they were enabled.

The United States government created the system, maintains it, and makes it freely accessible to anyone with a GPS receiver.

A true hardware GPS receiver doesnt need an internet connection to function.

Some Android devices today come with an A-GPS (Assisted GPS) that makes the process of finding a GPS Sattelite faster, it is a receiver that uses the cellular towers.

Very often cellular network towers have GPS receivers (or a base station nearby) and those receivers are constantly pulling down satellite information and computing the data.

This data is then passed on to the cellular phone an internet connection to function so pay attention when reviewing a specific device and if you plan to utilize it in areas where connection is or is not available.

For that reason the GPS receiver is not always open but is being asked by the Android OS to open the antennas for reception only once in a while at a certain frequency (depending the App that is asking for location information).

Hence, when using known navigation apps (Waze for example) you can notice your battery power is being consumed very fast.

In this operation mode the Android OS constantly receives the latest GPS location received from the GPS receiver on your device.

If located within any indoor building, the GPS will not be able to receive its location transmissions transmitted by the GPS satellites, as the transmissions just cant go through the walls and are being blocked.

It does it by querying its available resources as available on the device and as been defined in the location services definitions (GPS, WiFI, 3G).

An App on the device can instruct the Android OS to request more or less frequent sampling if required.

The Android OS will provide the App the latest most accurate location it received.

Location data is used for quality control purposes, understanding where the field it is at during the project and other specific survey related needs such as specifying Geo locations the interviewer is passing through during the interview.

The default frequency is 5 minutes, meaning that from the moment you have opened SurveyToGo, every 5 minutes SurveyToGo will ask for the latest location obtained by the Android OS.

You can change this sampling rate if a more frequent sampling is required based on your surveying needs.

Please note that higher frequency means higher battery consumption.

As explained it ensures an accurate positioning but will be less available in certain cases (when interviewing indoors etc).

This allows you to later verify that the interviews was indeed collected where plannedrequired.

You can the review this data when reviewing the interview on the Operations Console or when exported.
