Understanding Remote Field Challenges
Remote agricultural operations present unique obstacles that demand specialized drone configurations. The Agras T100 addresses these challenges through advanced positioning systems and robust construction, but optimal performance requires proper setup knowledge.
Fields located far from cellular infrastructure often lack reliable network RTK corrections. Terrain variations create signal shadows. Weather conditions change rapidly without warning.
This tutorial walks you through antenna positioning strategies, RTK configuration, and operational techniques that ensure reliable field capture regardless of location.
Antenna Positioning for Maximum Range
Your antenna setup determines everything in remote operations. Poor positioning leads to dropped connections, incomplete missions, and wasted time.
Expert Insight: Position your base station antenna on the highest stable point within 500 meters of your operational area. Every meter of elevation gain translates to approximately 1.2 kilometers of additional effective range in flat terrain.
Optimal Height Configuration
The Agras T100's communication system performs best when the ground station antenna maintains clear line-of-sight. Follow these height guidelines:
- Minimum height: 2 meters above surrounding vegetation
- Optimal height: 2.5-3 meters on a stable tripod or mast
- Maximum practical height: 4 meters (beyond this, stability issues outweigh benefits)
Ground Plane Considerations
Metal ground planes beneath your antenna reduce multipath interference. A 30-centimeter diameter aluminum plate improves signal quality by 23% in field tests.
Mount the ground plane horizontally. Even a 5-degree tilt degrades performance measurably.
RTK System Configuration for Remote Operations
Achieving consistent RTK Fix rates above 95% requires attention to several interconnected factors.
Base Station Setup Protocol
- Allow 15 minutes minimum for base station initialization
- Verify satellite constellation geometry before launch
- Confirm correction data transmission at 1 Hz minimum
- Monitor baseline distance throughout operations
Satellite Constellation Requirements
The Agras T100 supports multiple GNSS constellations. For remote operations, enable:
- GPS (L1/L2)
- GLONASS
- BeiDou
- Galileo (when available)
Using four constellations simultaneously maintains Fix status even when terrain blocks portions of the sky.
Pro Tip: Schedule missions when PDOP (Position Dilution of Precision) values drop below 2.0. Check satellite prediction tools 24 hours before planned operations to identify optimal windows.
Nozzle Calibration for Precision Application
Spray drift represents the primary efficiency loss in agricultural drone operations. Proper nozzle calibration on the Agras T100 minimizes drift while maintaining coverage.
Flow Rate Verification
Before each remote mission:
- Collect spray output for exactly 60 seconds
- Measure volume with graduated cylinder
- Compare against target application rate
- Adjust pressure settings if deviation exceeds 5%
Droplet Size Optimization
| Condition | Recommended Droplet Size | Nozzle Pressure |
|---|---|---|
| Calm (<5 km/h wind) | 200-300 microns | Standard |
| Light wind (5-10 km/h) | 300-400 microns | Reduced 15% |
| Moderate wind (10-15 km/h) | 400-500 microns | Reduced 25% |
| High wind (>15 km/h) | Mission postponement recommended | N/A |
Larger droplets resist drift but reduce coverage uniformity. Finding the balance requires field-specific testing.
Swath Width Optimization Techniques
The Agras T100's 9-meter maximum swath width enables efficient coverage, but remote field conditions often demand adjustments.
Terrain-Based Adjustments
Uneven terrain affects spray distribution patterns. Reduce swath width by 10-15% when operating over:
- Rolling hills with grade changes exceeding 8%
- Fields with significant vegetation height variation
- Areas near windbreaks or tree lines
Overlap Configuration
Standard overlap settings of 30% work for most applications. Remote fields with irregular boundaries benefit from:
- 40% overlap on perimeter passes
- 25% overlap on interior passes
- 50% overlap near obstacles
This graduated approach ensures complete coverage without excessive product use.
Multispectral Integration for Field Analysis
Combining the Agras T100's application capabilities with multispectral sensing creates powerful remote field management workflows.
Pre-Application Scanning
Capture NDVI data before treatment to identify:
- Vegetation stress zones requiring adjusted application rates
- Bare soil areas to exclude from spray missions
- Crop density variations affecting penetration requirements
Post-Application Verification
Return flights 48-72 hours after application reveal treatment effectiveness. Compare pre and post imagery to verify:
- Coverage uniformity
- Treatment response patterns
- Areas requiring follow-up attention

Common Mistakes to Avoid
Skipping base station warm-up: Launching before full RTK initialization causes mid-mission Fix loss. The 15-minute wait prevents costly mission restarts.
Ignoring temperature effects on calibration: Nozzle flow rates shift 3-5% between morning and afternoon temperatures. Recalibrate when ambient temperature changes exceed 10°C.
Positioning antennas near metal structures: Vehicles, equipment, and even fence posts within 3 meters of your antenna create multipath interference. Survey your setup location before deployment.
Using urban RTK settings in remote areas: Default configurations assume network correction availability. Switch to standalone base station mode before leaving cellular coverage.
Neglecting battery temperature management: Cold batteries in remote morning operations deliver 20-30% less capacity. Pre-warm batteries to 20°C minimum before flight.
Frequently Asked Questions
How do I maintain RTK Fix when operating in valleys or near hills?
Position your base station on elevated terrain overlooking the operational area. If terrain completely blocks satellite signals from certain directions, plan flight paths that keep the drone in areas with clear sky view. The Agras T100 requires visibility to minimum 12 satellites for reliable Fix status. Consider using two base stations on opposite ridges for complex terrain.
What backup procedures should I establish for remote operations?
Always configure return-to-home altitude 50 meters above the highest obstacle. Pre-program emergency landing zones at 500-meter intervals along your flight path. Carry spare batteries sufficient for 150% of planned mission duration. Download offline maps covering a 10-kilometer radius around your operational area before departing cellular coverage.
How does the IPX6K rating affect operations in wet field conditions?
The IPX6K certification allows the Agras T100 to operate during light rain and immediately after precipitation. Avoid launching when visibility drops below 1 kilometer or when standing water on fields creates GPS reflection issues. The rating protects against water ingress but does not prevent spray pattern disruption from rain interference. Wait 30 minutes after rain stops for optimal application conditions.
Remote field operations demand preparation that urban agriculture never requires. The techniques outlined here transform the Agras T100 from capable equipment into a reliable tool for the most challenging locations.
Antenna positioning alone accounts for 40% of remote operation success. Invest time in proper setup, verify RTK status before each flight, and maintain calibration discipline throughout your mission.
