Low-light and no-light aerial navigation

A method comprising:

• determining, by one or more processors of an aerial vehicle, and based on sensor information received from at least one onboard sensor, that an amount of light fails to satisfy a light threshold;
• based at least in part on determining that the amount of light fails to satisfy the light threshold causing, by the one or more processors, the aerial vehicle to takeoff at a specified trajectory and a specified acceleration for enabling navigation via an inertial measurement unit (IMU) and a satellite positioning system;
• and
• directing the aerial vehicle to navigate an environment based at least on determining a relative heading of the aerial vehicle from information received from the IMU and information received from the satellite positioning system.

One or more non-transitory computer-readable media storing instructions executable by one or more processors of an aerial vehicle to cause the one or more processors to:

• determine, based on sensor information received from at least one onboard sensor, that an amount of light fails to satisfy a light threshold;
• based at least in part on determining that the amount of light fails to satisfy the light threshold, cause the aerial vehicle to takeoff at a specified trajectory and a specified acceleration for enabling navigation via an inertial measurement unit (IMU) and a satellite positioning system;
• and
• direct the aerial vehicle to navigate an environment based at least on determining a relative heading of the aerial vehicle from information received from the IMU and information received from the satellite positioning system.
