Sorry, but that is not correct. GPS signal to the controller is not relevant to how the drone flies. Controller GPS is used for distance read out and the Return to Controller function. The only time I will wait for controller GPS to have ANY satellites is when I need distance readings for range testing. I rarely wait more than 1 minute before any flight , waiting only for the craft GPS indicator to turn green. If GPS on the controller mattered, how could indoor flight be achieved?
two systems the visual (camera) and sonar on the bottom of the RealSense Module. This feature fixes the position and altitude of the Typhoon H Plus which allows for indoor flights. In Angle Mode ONLY.
Note
Caution:
DO NOT tap the icons [ ] or [ ] in IPS mode, which could cause damage to the aircraft.
In Angle Mode, if the aircraft (FC) system initiates the IPS mode [as it cannot get a good GPS signal] the ST16S informs
the pilot by a pop-up message the system is in IPS mode. “IPS Activated”
While in IPS mode, the aircraft CAN NOT be switched to Sport Mode, RTL (Home) Mode or a Task Mode; it will ONLY remain in Angle Mode even if you try to switch the flight mode switch to a different mode.
Note
With IPS activated, OBS AVOID is NOT available.
When IPS is active to lock the position of the aircraft (not GPS), the H Plus will be able to hover at its current altitude
automatically (like with GPS). The maximum flight speed is 8.9mph (4m/s).
Note
When using IPS, ensure indoor illumination is sufficient - as the IPS system may not be able to position the aircraft if flying over highly reflective surfaces or over highly repeated surface textures (such as the same color).
OBSTACLE AVOIDANCE (Read the Precautions at the back of the Manual)
With a sustainable GPS, Obstacle Avoid can ONLY be activated in Angle mode.
WARNING!!
OBSTACLE AVOID is not available below 5ft (1.5m).
If an obstacle moves towards the Typhoon H Plus, the aircraft will not avoid it. i.e. Children, Pets etc.
Is a 3-position switch on the upper right of the ST16S, the Top position is OFF, Middle and Bottom positions is ON. When the Obstacle Avoid is activated, the front two motor LEDs will Flash white and the ST16S screen will display
a [ ] icon in the top information bar. You will also get a screen pop up ‘OBS activated’ for a sec or two. Note
When the icon [ ] is displayed on the ST16S screen, it means - Obstacle Avoid function is activated. ex. If below 5ft (1.5m) this icon will disappear & you will get a warning
Note
Obstacles can only be detected in the front (55o FOV), Detection range is approximately 15ft (5m) to 30ft (10m) it CAN NOT detect side, rear or overhead obstacles.
The speed of the aircraft will be limited with OBSTACLE AVOID ON.
If camera is removed – the front white LEDs will flash, indicating OBSTACLE AVOID is ON, you will not get an icon in the top information bar or the sonar bar display.
IPS Mode is not switch selectable – the Typhoon H Plus flight control system will activate
this mode if it cannot find any GPS Satellite
