getSite()
No parameters
Returns landing site geoposition.
getImpact()
No parameters
Returns impact geoposition.
lngError()
No parameters
Returns longitude difference between impact longitude and desired landing longitude.
latError()
No parameters
Returns latitude difference between impact latitude and desired landing latitude.
errorVector()
No parameters
Returns a vector between desired landing position and current impact position.
overshoot(int)
Parameters:
- meters::Integer -> by how many should I overshoot original landing position?
Returns new landingDataModel object with landingSite parameter shifted by distance defined in meters, in the direction of flight.
Code examples
Give code examples
// before flight, we will choose a target(could be a mobile landing pad)
wait until hastarget.
local ldata is landingDataModel(target:geoposition).wait until hastarget.
local ldata is landingDataModel(target:geoposition).
.
.
.
print ldata["errorVector"]():mag. // prints how far impact point is from target
// in meterswait until hastarget.
local ldata is landingDataModel(target:geoposition).
.
.
.
// creating new landingDataModel, but the landing position
// is being shifted by 50 meters in the direction of flight
// from original landing position
local overshootData is ldata["overshoot"](50).
