Hi there, it looks like the light is too weak for VPS, is there any chance change to another environment with the bright light? You may check the working conditions of VPS from here: https://dl.djicdn.com/downloads/mavic/Mavic%20Pro%20User%20Manual%20V2.0-.pdf
BTW, it seems that you started two posts almost at the same time, we'll merge them here as this violates the forum regulations, please kindly note and understand.

Are you flying drone outside, while sun is up, and in an area with open sky (no trees or buildings or obstructions that could block GPS signals)?

Calibration of Mavic Pro front & bottom vision sensors should be done inside using good PC / Laptop screen.
It would be worth making sure the vision sensors do not have any smudges or dirt on lens causing problems.

Being you have a Mavic Pro, you can rollback from current (.0400) firmware to previous firmware version you were running (.0300 or .0200 or .0100) using DJI's Assistant-2 ---- to see if Vision and GPS problems go away.  Don't forget to roll back Remote Controller too.

You need to download DJI's Assistant-2 for either Microsoft Windows or Apple's OS-X.
DJI Assistant-2 is not ''Blessed'' by Microsoft or Apple, and Assistant-2 has un-signed USB drivers.
Windows will not install Assistant-2 unless you disable security in PC's BIOS.
Assistant-2 has to be installed with Administrator privileges on either Windows or OS-X.

Once Assistant-2 is successfully installed, with Mavic Pro powered on, and Assistan-2 running, you connect Mavic Pro to PC or Mac using microUSB to USB cable.  Assistant-2 will show un-plugged USB cable connecting to computer.  From there Assistant-2 will change screen showing box with your drone (Mavic Pro).  Select box and new screen appears with numerous options.  One of which is Firmware screen.
From Firmware screen you can rollback or upgrade Mavic Pro Firmware.

After rolling back Mavic Pro firmware, make sure to roll back Remote Control firmware to same revision.

Hi, sorry for the troubles that it caused. I would like to ask what happen prior to this issue? Have you done calibrating the sensor of your drone using the DJI Assistant 2? If not, I would recommend downloading the application for you to calibrate it. Please see the link for you to download the DJI Assistant: https://www.dji.com/mavic/info#downloads Please see the video below for you to have an idea on how you will calibrate the vision sensor. Thank you.

Unless you are ready to return drone, you might as well try refreshing current firmware.  
Or rolling firmware back to .0200 or .0100.
Then try calibrating vision sensors.
