Assuming the P3 uses the same technology as the Inspire, what is the effectiveness of the system used outside with no GPS.........is it effective and at what altitude?

The Inspire specs appear to provide a 16 ft max altitude! (500cm)

Vision Positioning

Velocity Range

Below 8 m/s (2 m above ground)
Altitude Range
5-500 cm
Operating Environment
Brightly lit (lux > 15) patterned surfaces
Operating Range
0-250 cm

Well ... in the P3 specs it says ...
Altitude Range
30 cm-300 cm

I wonder about the figure in the specs for the Inspire.
Elswhere it described as ...
The effective hovering altitudes of the aircraft is from 0 to 2.5 meters.

More dubious specs. Meta4... No???

The reflectance of the target will determine the effective range.

A downside to ultrasonic sensors is that sound absorbing materials make poor target objects.

Here's to hoping that someone bright out there will kickstart an optical sensor that could be retrofitted to P2's and other non-Naza-based mulit-rotors. I can't imagine the DJI components being offered for the P2,P2V,P1 platforms. Voltage issues, firmware issues, and no market incentive to do so.
