2.4 Power supply

T30 GNSS receiver supports internal batteries and external power input.
2.4.1 Internal batteries
The receiver is equipped with two rechargeable Lithium-ion batteries, which can be
removed for charging. The T30 receiver adopts the hot swap battery design that
provides you an effective survey workflow. The internal batteries typically provide
about 12-hour operating time as a rover, about 7-hour operating time if operated as
a base station with internal UHF Tx (transmit at 1-2 watts). However, this operating
time varies based on environmental conditions.
 Battery Safety
Charge and use the battery only in strict accordance with the instructions below:
– Do not use or charge the battery if it appears to be damaged. Signs of damage
include, but are not limited to, discoloration, warping, and leaking battery fluid.
– Do not expose the battery to fire, high temperature, or direct sunlight.
– Do not immerse the battery in water.
– Do not use or store the battery inside a vehicle during hotweather.
– Do not drop or puncture the battery.
– Do not open the battery or short-circuit itscontacts.
 Charging the Lithium-ion Battery
Although a dual battery charge is provided, the lithium-ion battery is supplied
partially charged. To charge the battery, first remove the battery from the receiver,
and then place it in the battery charger, which is connected to AC power. Please
obey the following instructions when charging your batteries:
– Charge the battery completely before using it for the first time.
– Fully charge takes approximately 6 hours per battery at room temperature.
– If the battery has been stored for a long time, charge it before your field work.

5.8.1 Point to Point/Points mode (P to PS mode)

In point to point mode, the correction data is transmitted from the base station to
the Server, then rovers can log on the Server to get the correction data. Therefore,
SIM cards are required both in the Base and Rover.

Tip: ComNav technology provides a free static server address 211.144.120.104:8888, anyone can
upload CORS data as long as abide by the agreement.

Below shows Base configuration with ComNav server:

 Server: select SINOGNSS server(IP: 211.144.120.104 and Port:8888)
 BaseName: Click BaseName to get SN of Base receiver directly, when start
Rover, just select the name as source
 Differential mode: make sure to choose RTCM32
 Fix Position: Click Library choose to select a known point for the Base, or Get
from GNSS if you do not have a known point.

After successfully starting the Base station:

1) The differential LED (yellow) flashes once per second, which means the Base is
broadcasting correction data;
2) The internal 4G LED (blue) flashes once per second, which shows that the
correction data is transferred via GPRS network.

29
 SinoGNSS○R T30 User Guide

Tip: Normally the blue LED flash once every five-second, it indicate WIFI function, when flash
once per second shows GPRS is working.

Configure the Rover as below:

 Protocol: Select SINOGNSS directly;
 BaseName: Enter the SN of the Base receiver.

5.8.2 Internal 4G Ntrip client mode

For Ntrip client mode, Rover acquires correction data from Ntrip(CORS) server.

6.1.2 Bubble setting for Tilt survey

Bubble option will appear when receiver supports for tilt survey, it is available for
ComNav Technology T30 GNSS receiver, but T300 does not support tilt survey.

When the pole tilts within 30°, the built-in sensor based tilt measurement system
precisely calculates the actual offset according to angle, which can not only meets
the requirement of high precision measurement, but also relieves the users from
continually checking whether the pole is plumb.

33

T30

T300

1. Check Bubble option: Go into Topo survey—Settings—Bubble

 Tilt tolerance: the value is relevant with the antenna height, if antenna height is
2m, the tilt should be less than 1m (tilt angle should less than 30°)
 Magnetic field strength: default value is 70, You can check current field
Magnetic strength: Device → Position Info. Please kindly adjust it, the bigger
value of magnetic field strength is, the more increase of measure error will be.

2. Calibration

If calibration expired or you first use the receiver, tap Calibrate and follow the
guidance until succeed. During operation, make receiver can search the satellites.

34
 SinoGNSS○R T30 User Guide

Magnetometer calibration:
 Operate as the picture
shows.

Accelerometer calibration:
 Mount the receiver on a
leveled tribrach. Be sure
the receiver is definitely
on level. This step is very
important for receiver to
get high accuracy.

In survey interface, you can find the bubble and angle value shows the pole you tilt.
The angle should be less than 30°, for more accuracy, angle less than 15°will be
better.
