VisNav Mission Planner

Planner API: checking…

Instrukcja — 1. Fetch winds. 2. Move cuts (Jetson box follows). 3. Download USB, as many times as you want.

1. Launch window

Launch time (UTC) Operator laptop time, written into winds_esp32.bin as t0. Jetson has no Wi-Fi in flight and must not replace this clock.

Duration (h)

Cruise altitude (m) Constant-level float used for planning. ESP still interpolates the pressure cube from baro in flight.

Altitude tolerance ± (m) Re-integrates the GFS control track at cruise−Δ and cruise+Δ (not an ensemble mean). Shows how a density-altitude error would shift the miss. Brown dashed lines on the map.

Wake lead (km / min) Jetson powers on when dead reckoning enters this box: the cut plus this lead, not the whole flight. The box is capped at 50 000 km² and is kept off the launch pad. A 30 h track does not make a 30 h wake zone. Timeout is the backup if the box is missed.

Wake timeout cap (h) Hard safety ceiling for battery protection. Simulation sets the actual wake timeout earlier (cut time + 2h); this cap guarantees Jetson wake on abnormal delays while capping maximum battery drain.

Ascent rate (m/s) Tropospheric vertical ascent velocity from surface to cruise altitude (e.g. 5.0 m/s = 300 m/min). Set to 0 for instantaneous cruise float. Crucial for realistic ground launch coordinate solution.

2. Launch and cut

Solve launch from primary cut Reverse-integrates control winds from the primary cut for the forecast duration, then flies control + ensemble forward from that start. Launch lat/lon become read-only. Wind domain must cover the reverse track; a start outside the cube is edge-clamped wind, not a real pad.

Launch lat

Launch lon

Default pad: Toruń Space Labs, Łokietka 11–17.

Cut targets — first is primary (reverse + labels). Jetson fires the cutter on the first radius entered (OR).

3. Wind domain

North

South

West

East

GEFS ensemble members GEFS members around the GFS line (default 8, max 30). They load after the blue track is already on the map. USB still packs GFS 0.25° only. More members tighten the confidence interval; they do not change the USB winds. A long flight is GO only when this spread fits inside the cut circle.

4. Jetson wake box & emergency backup

Wake north

Wake south

Wake west

Wake east

Auto emergency timeout (cut time + 2.0 h backup margin) If the balloon misses the geofence, ESP forces Jetson power-on after this duration to attempt visual acquisition and cutter activation before battery exhaustion. Uncheck to adjust manually.
