• The mojoRTK works with a lightweight and easy-to-transfer mobile base station
that provides highly reliable accuracy without incurring GPS subscription fees. The
unique and compact design of the mojoRTK allows you to move it from one piece
of equipment to the next, covering your entire fleet. This is easily accomplished
by the patented design and installation into a DIN slot or radio receptacle.
• Beyond its capabilities of steering accuracy, the mojoRTK also provides remote
service and diagnostics for your guidance system and agricultural machinery,
remote upgrades, and 24/7 service and assistance, eliminating costly on-site
service calls.

Charging / first-time use
• The batteries must be charged prior to using for the first time because it is delivered with an energy content as low as possible.
• The permissible temperature range for charging is between 0°C to +35°C /+32°F
to +95°F. For optimal charging we recommend charging the batteries at a low
ambient temperature of +10°C to +20°C/+50°F to +68°F if possible.
• It is normal for the battery to become warm during charging. Using the chargers
recommended by Leica Geosystems, it is not possible to charge the battery if the
temperature is too high.
• For new batteries or batteries that have been stored for a long time (> three
months), it is effectual to make only one charge/discharge cycle.
• For Li-Ion batteries, a single discharging and charging cycle is sufficient. We
recommend carrying out the process when the battery capacity indicated on the
charger or on a Leica Geosystems product deviates significantly form the actual
battery capacity available.
Operation/Discharging
• The batteries can be operated from -20°C to +55°C / -4°F to +131°F.
• Low operating temperatures reduce the capacity that can be drawn; very high
operating temperatures reduce the service life of the battery.
Warning Batteries not recommended by Leica Geosystems may be damaged if charged or
Leica mojoRTK, mojoRTK Base Station Operation 43
discharged. They may burn and explode.
Precautions:
Only charge and discharge batteries recommended by Leica Geosystems.

• Standard use setup would configure the tripod as high as possible with the legs
at maximum distance.
• Sandbag or weight the tripod to improve the stability of the base station.
• Protect the base station from animals and farm equipment.
• Be aware that other equipment may interfere with the base station. This includes
but is not limited to generators, radio transmitters, electrical equipment, and
other base stations.
• The base station should be mounted on the tripod or be fixed in the open. It
should not be placed under or near roofs, trees, large bodies of water, or
awnings. Any obstacle may affect GPS and radio transmissions.
• The base station requires line of sight to the console. Vehicles, buildings, solid
fences, or trees can all affect operation.
• When using the base station as a permanently installed reference station a
power cable can be purchased for power supply and no batteries are needed.

74
General information
The tuning of the mojoRTK is preloaded based on your selected vehicle/steering kit
type and should be a reasonable starting point for tuning refinement. To refine the
tuning of the system, there are four parameters:
• Sensitivity
• Aggressiveness
• Overshoot
• Speed Adjust
For optimal performance, the system tuning must be refined for your steering
kit/vehicle.
5.1 Tuning Wizard
General information
Leica mojoRTK, Tuning 75
Sensitivity, Aggressiveness, Overshoot, and Speed Adjust can be found in the Vehicle
Tuning Wizard.
• Get the following parameters right at 5 km/h / 3 mph and then you should only
have to adjust speed.
• Settings in the Tuning Wizard are applied immediately but not saved unless
is pressed.
• Some steering kits/vehicles do not require tuning, so this wizard may be replaced
by a specific one for your selected steering kit/vehicle.

5.2 Sensitivity
76
Setting the Sensitivity
The sensitivity will control the rate that the tractor turns and how sensitive it is when
it is on the line. Sensitivity should be the only parameter that you need to adjust to
adapt the control performance to the current working conditions after the tuning
refinement is done.

5.6 Tuning Tips
82
General tuning tips When dealing with the tuning, each parameter must be treated separately, even
In-depth tuning
tips
though they may have interactions between them.
When tuning for:
• turning rate and twitch on the line, use Sensitivity.
• line holding, oscillations, and line approach speed, use Aggressiveness.
• amount of overshoot or undershoot, use Overshoot.
• variation over speed, use Speed Adjust.
Get these parameters right at 5 km/h / 3 mph, and then tune for higher speeds with
only the Speed Adjust.
Symptom Resolution
Tractor is too slow to approach the line. Increase the Aggressiveness.
Tractor is too fast to approach the line or
the tractor oscillates.
Tractor straightens up before it gets to
the line.
Decrease the Aggressiveness.
Increase the Overshoot.
Symptom Resolution
Tractor drives past the line then comes
back onto to the line.
Tractor turns very slowly to drive toward
the line.
Tractor turns very aggressively to drive
toward the line and twitches when on
the line.
Tractor oscillates only at higher speeds. Reduce the Speed Adjust.
Tractor does not hold the line at higher
speeds.

need for a local base station. The RTK corrections are instead received from a
network provider over the internet using the console’s internal modem. The Network
RTK feature replaces the local base station with a network of permanent base
stations operated by a network provider.
Network RTK offers very quick convergence times (similar to using the mojoRTK base
station) compared to other correction sources available.
The Network RTK base stations are survey quality and mounted in fixed positions,
offering repeatability from year to year.
Internet connections are only supported through the mojoRTK console’s internal
modem and so cellular coverage is required in all areas you intend to operate guidance.
In order to use Network RTK, it is necessary to be within the bounds of the network
being used. Only correction streams providing CMR, CMR+ or RTCM 3 format corrections are supported. GLONASS is only supported with the RTCM 3 format.
