Centimeter-Level RTK Accuracy

The V4e Pro is built for work where ordinary phone GPS is not precise enough.

With an RTK correction source, FJD specifies positioning accuracy of:

Horizontal: ≤0.8 cm + 1 ppm Vertical: ≤1.5 cm + 1 ppm

That level of precision makes it possible to create much more accurate boundaries, reference points, work zones, and field layouts than standard consumer GPS.

The receiver uses 1,408 parallel GNSS channels and supports signals from multiple global satellite constellations, including GPS, GLONASS, Galileo, BeiDou, QZSS, and SBAS.

Why That Matters

More accurate site data can mean:

• Better-defined robotic work areas
• More repeatable layouts
• Cleaner transitions between zones
• More precise reference points
• Less time correcting maps later
• Faster setup on repeat jobs

Measure Difficult Points Without Standing Directly Over Them

Not every point you need to map is easy to reach.

Fence corners, landscape beds, retaining walls, ditches, obstacles, wet areas, and other site features can make conventional point collection slow or awkward.

The V4e Pro combines an integrated IMU with laser-assisted measurement, allowing an operator to target points without needing to place the receiver directly on top of every location.

FJD specifies laser measurement accuracy of up to approximately 3 cm at a 3-meter distance under applicable conditions.

That can make mapping faster around:

• Trees
• Buildings
• Fences
• Landscape features
• Curbs
• Drainage areas
• Restricted spaces
• Uneven terrain

No Traditional Survey Pole Required for Many Tasks

Traditional GNSS surveying equipment can involve a receiver mounted on a pole that must be positioned and leveled at each point.

The V4e Pro was designed around a much more portable workflow.

Pick it up, connect it to your compatible device or controller, establish your RTK positioning, and begin collecting points.

The integrated IMU helps compensate for receiver angle during supported measurements, making field work quicker and more comfortable.

For crews that frequently move from property to property, the difference is significant: the mapping equipment can fit in your hand instead of becoming another large piece of equipment that has to be transported and set up.

Built for Long Days Outside

At only 320 grams, the V4e Pro is light enough to carry around a property without the fatigue associated with heavier surveying equipment.

Despite its small size, it is designed for outdoor field conditions.

Field-Ready Construction

IP67 Rated Protection against dust and temporary water immersion under the applicable IP67 test standard.

1.2-Meter Drop Protection Designed to survive the kinds of accidental drops that can happen during field work.

12+ Hour Battery Life Enough battery capacity for a full working day in many applications.

≤3 Hour Recharge Time Recharge quickly and get back into the field.

Operating Temperature: Approximately -20°C to 60°C (-4°F to 140°F).

Fast Startup. Less Waiting.

Field equipment should not become the bottleneck.

The V4e Pro is designed to establish positioning quickly, with FJD listing:

• Cold start: ≤30 seconds
• Hot start: ≤5 seconds
• RTK initialization: <5 seconds under appropriate conditions
• Signal reacquisition: ≤1 second

The result is a tool designed to spend more time collecting useful data and less time waiting for the receiver.

A Natural Tool for Robotic Grounds Management

The V4e Pro is especially interesting for organizations moving toward autonomous grounds maintenance.

Robotic equipment needs to understand where it is supposed to work.

The Trion gives operators a practical way to collect accurate outdoor positioning data before or alongside deployment of compatible FJD robotic equipment.

Potential Applications

Commercial Properties

Map mowing areas, obstacles, reference points, and property features before autonomous equipment is deployed.

Municipalities

Document parks, public grounds, recreation areas, athletic fields, and other maintained turf.

Schools & Universities

Create accurate layouts for campuses, athletic facilities, and large grounds-maintenance areas.

Golf & Sports Facilities

Collect precise field, turf, and site data for mowing, marking, or maintenance workflows.

Landscape Contractors

Map customer properties quickly and build a reusable digital record of each site.

Robotic Mower Dealers

Create a more professional mapping and installation workflow for larger or more complex properties.

One Compact Receiver. Multiple Workflows.

Depending on the software and equipment paired with it, the V4e Pro can support several different workflows.

Basic GNSS Mapping

Connect to a compatible mobile device and use the receiver for accurate field positioning and point collection.

Trion Survey

For more advanced surveying workflows, FJD’s Trion Survey software supports functions such as point measurement, stakeout, CAD/GIS workflows, coordinate systems, and data export.

FieldFusion

Pairing Trion hardware with FJD FieldFusion can support field-boundary mapping, data collection, and broader digital field-management workflows.

FJD Robotic Equipment

For organizations using compatible FJD landscaping and autonomous equipment, accurate digital mapping can become the foundation for mowing, marking, and property-management automation.
