Field Report: Coastal Delivery Operations in Maritime Environments
Coastal delivery operations present unique challenges that ground-based logistics simply cannot solve. The Agras T50 addresses these challenges with engineering specifically suited for maritime conditions—this field report documents our 12-week deployment along the Pacific Northwest coastline.
Our research team at the Coastal Operations Research Institute deployed three T50 units across 47 delivery missions to remote lighthouse stations, offshore research platforms, and isolated coastal communities. The results exceeded our initial projections by a significant margin.
The primary obstacle in coastal drone operations isn't distance—it's environmental unpredictability. Salt-laden air, sudden wind gusts, and rapidly shifting visibility conditions demand equipment built for punishment. The T50's robust construction proved essential throughout our testing period.
Environmental Challenges and T50 Capabilities
Salt Spray and Moisture Protection
Coastal environments destroy unprotected electronics within weeks. The T50's IPX6K rating provided complete protection against the high-pressure salt spray conditions we encountered daily.
During our November deployment, one unit operated through 23 consecutive days of coastal fog with zero moisture-related failures. The sealed motor housings and protected avionics compartments prevented the corrosion issues that plagued our previous drone fleet.
Key protective features we relied upon:
- Fully sealed propulsion system housings
- Corrosion-resistant aluminum alloy frame components
- Protected sensor arrays with hydrophobic coatings
- Drainage channels preventing water accumulation
- Reinforced cable connections with marine-grade sealing
Expert Insight: Apply a thin layer of ACF-50 anti-corrosion compound to all exposed metal surfaces before coastal deployments. This aerospace-grade protectant extends component lifespan by 60% in salt-air environments based on our maintenance records.
Wind Resistance and Stability
Coastal wind patterns shift without warning. The T50's 8-rotor coaxial design maintained stable flight in sustained winds up to 12 m/s with gusts reaching 15 m/s during our December trials.
The active gimbal stabilization system kept our payload orientation steady even during aggressive wind compensation maneuvers. This stability proved critical when delivering fragile medical supplies to the Heceta Head research station.
Precision Navigation in Coastal Terrain
RTK Positioning Performance
Coastal delivery demands accuracy that standard GPS cannot provide. The T50's RTK Fix rate consistently exceeded 98.7% across all mission profiles when paired with properly positioned base stations.
We established three permanent base stations along our 40-kilometer operational corridor. The T50 maintained centimeter precision positioning even when transitioning between base station coverage zones—a capability that surprised our navigation team.
The dual-antenna RTK system provided:
- 2 cm horizontal accuracy in open coastal areas
- 5 cm vertical accuracy for precise landing approaches
- Seamless handoff between RTK correction sources
- Automatic fallback to PPK processing during signal interruptions
Terrain Following and Obstacle Avoidance
Coastal cliffs and irregular terrain create dangerous flight conditions. The T50's multispectral sensing array detected obstacles at ranges exceeding 30 meters, providing adequate reaction time even at maximum cruise speeds.
The terrain-following radar maintained consistent 15-meter AGL altitude along cliff faces where barometric altitude would have caused dangerous altitude variations. This capability enabled safe operations in areas we previously considered unflyable.
Pro Tip: Configure terrain-following sensitivity to "High" when operating near cliff faces. The default "Standard" setting occasionally missed narrow rock outcroppings during our initial calibration flights.
Third-Party Integration: Herelink Ground Station Enhancement
Our most significant operational improvement came from integrating the Herelink 1.1 ground control system with the T50's native control architecture. This third-party accessory transformed our coastal delivery capabilities.
The Herelink system provided:
- Extended control range to 18 kilometers over water
- Dual-operator capability for complex delivery approaches
- HD video streaming at 1080p/60fps for precision landing
- Integrated telemetry display reducing pilot workload
- Physical control redundancy for safety-critical operations
The integration required custom firmware modifications, but the resulting system outperformed our expectations. Control latency remained below 120 milliseconds even at maximum range—essential for the precise maneuvering coastal deliveries demand.

Nozzle Calibration for Coastal Conditions
While our primary mission focused on package delivery, we also tested the T50's agricultural spray system for coastal vegetation management applications. The nozzle calibration process required significant adjustment for maritime conditions.
Salt-laden air affects spray drift patterns differently than inland operations. We discovered that reducing operating pressure by 15% and increasing droplet size settings produced more consistent coverage on coastal vegetation.
Calibration adjustments for coastal spray operations:
- Increase droplet VMD to 350-400 microns to reduce drift
- Reduce operating altitude to 2.5 meters in exposed areas
- Configure spray drift compensation for prevailing onshore winds
- Schedule applications during morning thermal inversions
- Verify nozzle flow rates after each salt-exposure flight
The T50's 16 electromagnetic nozzles maintained consistent flow rates throughout our testing despite the corrosive environment. We attribute this durability to the stainless steel construction and self-cleaning pressure cycling system.
Operational Workflow Optimization
Pre-Flight Procedures
Coastal operations demand rigorous pre-flight protocols. Our team developed a standardized checklist that reduced mission abort rates from 12% to under 3% across the trial period.
Essential pre-flight checks include:
- RTK base station signal verification
- Salt residue inspection on optical sensors
- Propeller blade edge condition assessment
- Battery terminal corrosion inspection
- Control link range testing before launch
Mission Planning Considerations
Coastal terrain requires careful mission planning that accounts for:
- Tidal variations affecting landing zone accessibility
- Marine layer formation timing and density
- Thermal wind pattern shifts throughout the day
- Wildlife activity zones requiring avoidance routing
- Emergency landing site identification along entire route
Common Mistakes to Avoid
Neglecting post-flight cleaning protocols. Salt accumulation causes progressive damage that manifests suddenly. Rinse all external surfaces with fresh water within 2 hours of coastal operations—no exceptions.
Underestimating marine layer density. Coastal fog reduces visibility faster than pilots expect. Establish hard abort criteria based on visibility distance, not subjective assessment. We use 500 meters as our minimum threshold.
Ignoring battery temperature management. Cold ocean air combined with high-current draw creates thermal stress. Pre-warm batteries to 25°C minimum before launch, and monitor cell temperature differentials throughout flight.
Relying solely on automated obstacle avoidance. The T50's sensors perform excellently, but thin cables and fishing lines remain detection challenges. Manually survey all approach corridors before automated flight.
Skipping redundant communication systems. Coastal radio propagation is unpredictable. Always configure backup control links and establish clear lost-link procedures before each mission.
Frequently Asked Questions
How does the T50 handle sudden coastal wind gusts during delivery approaches?
The T50's flight controller processes wind disturbance data at 400 Hz, enabling near-instantaneous compensation for gusts. During our trials, the system maintained position accuracy within 30 cm during gusts up to 15 m/s. The coaxial rotor design provides inherent gust resistance superior to single-rotor configurations, and the active stabilization system prioritizes payload orientation during wind events.
What maintenance schedule do you recommend for coastal operations?
We implemented a 50-flight-hour major inspection interval—half the standard recommendation for inland operations. This includes complete disassembly of motor housings, bearing inspection, and electrical connector cleaning. Daily maintenance requires fresh water rinse, optical sensor cleaning, and propeller edge inspection. Following this schedule, we experienced zero unplanned maintenance events across 47 missions.
Can the T50 operate effectively in rain during coastal missions?
The IPX6K rating protects against heavy rain exposure, and we successfully completed 8 missions during light to moderate rainfall. Heavy rain reduces optical sensor effectiveness for obstacle detection, so we recommend limiting operations to rainfall rates below 10 mm/hour. The RTK positioning system maintains full accuracy regardless of precipitation, ensuring navigation reliability even when visibility decreases.
