RangeSight

RangeSight is a pre-flight planning tool built for drone operators who need more than a gut feeling before takeoff. The physics-based RangeIQ algorithm runs the numbers on wind, battery, payload, and return-to-home requirements — and gives you a straight go or no-go answer before you ever arm the motors.

WHAT'S NEW IN 2.0

• RangeIQ+ Mission Analysis — waypoint-by-waypoint battery, return-margin, and smart RTH prediction

• Multi-format mission imports — KML, KMZ, GPX, CSV, WPML, LCHZ

• Live Weather + Personal Weather Station (WU PWS) integration

• Offline Map Downloads for any region at any zoom

• Custom Drone Builder with Simple, Advanced, and Expert modes

• Payload weight modeling for cameras and accessories

HOW IT WORKS

1. Pick your drone (or build a custom one), enter your battery, payload, and home location

2. Choose a destination, draw a mission, or import a flight file

3. RangeIQ pulls live weather, simulates the round trip against your aircraft's performance curve, and shows your safe range — leg by leg

4. See the result on the Range Analysis map: safe zones, warning zones, and a hard no-go boundary based on your battery reserve

KEY FEATURES

• Physics-based range model — not a generic "30% reserve" rule

• Multi-format mission file imports

• Offline maps for any region, any zoom

• Five Tuna Calibration to fine-tune predictions per drone

WHO IT'S FOR

Commercial drone pilots, surveyors, search-and-rescue teams, and serious hobbyists who fly far enough from launch that "looks fine" isn't a flight plan.
