Automatic insertion of POI through software for a drone to follow

We are interested to buy an autopiloted drone with the following capabilities:

1) To interconnect it through a USB cable with a tablet (Android 4.2, or later, or a PC) and an application produces the POI for the drone to follow, as a time series.  The desired POI, for the drone to follow, are produced in a form as follows:

Latitude at time 1: 41. XXXXX, Longitude at time 1: 24.XXXXXX, Altitude at time 1: 0.XXXXXX

Latitude at time 2: 41. XXXXX, Longitude at time 2: 24.XXXXXX, Altitude at time 2: 1.XXXXXX

Latitude at time 3: 41. XXXXX, Longitude at time 3: 24.XXXXXX, Altitude at time 3: 2.XXXXXX

Latitude at time 4: 41. XXXXX, Longitude at time 4: 24.XXXXXX, Altitude at time 4: 4.XXXXXX

.e.t.c..

until a target point to be reached. We need to know if this list of POI can be transfered to the drone controller through the software together with the take-off command and the drone to follow them until the target point and then to return to the home position and to touch-down following the reverse  trajectory, without our intervention.

 2) The drone must have the capability to carry a payload of at least 3kgrs

 3) It must have the capability to release the payload (for example a lifebuoy) under the command of the controlling tablet (or PC).

 Please, is there available such product?
