RTK GPS for Vineyards: PinPoint RTK vs Sentinel Vine Manager
If you have been researching vineyard GPS tools, you have probably come across two names: VineView's PinPoint RTK and Sentinel Vine Manager. Both use RTK GPS technology. Both are designed for vineyards. But they are built for fundamentally different purposes, and understanding the distinction will save you from buying the wrong tool.
This post compares them fairly. PinPoint RTK is good hardware. Sentinel is a full management platform. Depending on what you need, the right answer might be one, the other, or both.
What Is RTK GPS and Why Does It Matter for Vineyards?
RTK stands for Real-Time Kinematic. It is a satellite positioning technique that achieves sub-centimeter accuracy by using a fixed base station to correct the signal received by a rover unit. Standard GPS is accurate to a few meters -- fine for navigation, not fine for mapping individual vines spaced 4 to 6 feet apart.
Sub-centimeter RTK GPS means you can assign a permanent, unique coordinate to each vine. That coordinate does not drift between seasons. It anchors a digital record that follows the vine for the life of the vineyard -- not the life of the person who planted it.
For disease management, this matters. Leafroll virus and red blotch spread in spatial patterns. If your virus data is block-level, you cannot see whether the pressure is in one corner of a 3-acre block or spreading across the slope in a directional pattern. Vine-level GPS records make that visible.
VineView PinPoint RTK: What It Is
VineView is an aerial vineyard imaging company. PinPoint RTK is their ground-truth data collection hardware -- a GPS rover unit designed to let vineyard crews walk rows and record vine-level observations in the field.
What PinPoint RTK does:
- Provides sub-centimeter GPS accuracy for field data collection
- Allows crews to log observations (vine health, vigor, disease flags) tied to precise coordinates
- Designed for use alongside VineView's aerial NDVI and thermal imaging data
- Compatible with VineView's data visualization platform
Price: $399 for the hardware unit
What it does well: PinPoint RTK is purpose-built hardware. It is compact, affordable, and integrates cleanly with VineView's existing aerial analytics workflow. If you are already a VineView customer and want to add ground-truth GPS verification to your aerial data, this is a natural fit.
What it does not include: PinPoint RTK is hardware. It is not a vineyard management platform. It does not include work order management, spray log compliance, replant tracking, cellar integration, or ongoing vine history recordkeeping. The data it collects lives in VineView's ecosystem -- useful for their analysis workflow, but not a standalone vineyard management system.
Sentinel Vine Manager: What It Is
Sentinel Vine Manager is a vine-by-vine vineyard management platform. The RTK GPS data collection is the foundation -- but the platform is what you build on top of it.
What Sentinel includes:
- RTK GPS mapping with sub-centimeter accuracy (using Emlid Reach RX2 hardware -- available for $399)
- Permanent vine-by-vine digital records anchored to GPS coordinates
- Disease tracking at the individual vine level (leafroll, red blotch, Fanleaf, powdery mildew)
- Work order management tied to specific vine selections
- Spray log with California PUR compliance export
- Replant documentation -- new vine GPS coordinates replace removed vines in the same record
- Cellar integration -- lot tonnage and harvest data linked back to the specific vines that produced it
- Historical record that persists through staff turnover
Price: Starting at $5,000/year for estates up to 100 acres, scaling with acreage. Hardware (Emlid Reach RX2) is a one-time $399 purchase -- the same price as PinPoint RTK.
What it does well: Sentinel is designed to be the permanent operating record for a vineyard. The GPS coordinates are the scaffolding; the value compounds over time as the vine history builds.
Side-by-Side Comparison
| | PinPoint RTK | Sentinel Vine Manager | |---|---|---| | GPS accuracy | Sub-centimeter RTK | Sub-centimeter RTK (Emlid RX2) | | Hardware cost | $399 | $399 (Emlid Reach RX2) | | Software / platform | VineView ecosystem | Full vineyard management platform | | Vine-level disease tracking | Via VineView imaging | Yes, field-logged per vine | | Work order management | No | Yes | | Spray log / PUR compliance | No | Yes | | Replant documentation | No | Yes | | Cellar integration | No | Yes | | Standalone system | No (requires VineView) | Yes | | Annual cost | VineView subscription + $399 hardware | From $5K/yr + $399 hardware |
Which Is Right for You?
Choose PinPoint RTK if:
- You are already a VineView aerial imaging customer
- You want to add GPS ground-truth to your existing aerial workflow
- Your primary need is NDVI and thermal imaging, with GPS verification as a supplement
Choose Sentinel Vine Manager if:
- You want a standalone vine-by-vine management platform, not just hardware
- You need work orders, spray logs, disease records, and replant documentation -- all tied to GPS coordinates
- You want a vineyard record that compounds over time and survives staff turnover
- You are managing 50+ acres where block-level averages are losing you money in precision decisions
Both tools use RTK GPS. The difference is what happens after the GPS coordinate is recorded. PinPoint RTK feeds VineView's imaging workflow. Sentinel builds a permanent operating record of the vineyard.
The Bottom Line
RTK GPS accuracy is now accessible to any vineyard operation -- the hardware is $399 either way. The question is not whether to use RTK GPS. The question is what you want to do with the data.
If the answer is ground-truth verification for aerial imagery, PinPoint RTK is a clean, affordable option within the VineView ecosystem.
If the answer is a permanent, vine-by-vine operating record -- disease history, work orders, spray compliance, replant documentation, harvest data -- Sentinel Vine Manager is built for that.
