# Maintenance {% hint style="warning" %} When GOBI is powered indoors, GRYFN recommends pointing a small fan at the main exhaust vents to help keep thermals in check. GOBI maintains good temperatures in flight with sufficient airflow across the chassis, but can become quite hot when sitting powered in stagnant air for extended periods of time. {% endhint %} ## Storage and Handling GOBI should be stored in its rugged travel case in an air conditioned environment. Take care not to roughly handle the chassis as this can cause negative impacts on the boresight calibration. When storing GOBI and the aircraft, take care not to crimp GNSS cables, power cables, or network when closing the rugged cases. ### Traveling with GOBI GOBI comes in a rugged case meant for transportation. This case should keep it safe from damage. Choosing to transport GOBI via other methods is your choice; however, GRYFN recommends you transport GOBI in a well-fit and shock absorbent container. ### Safe Operating Temperatures 32F - 104F When powered inside, to prevent excess heat that could damage internal electric components or sensors themselves, we recommend running a small indoor fan aimed directly at the chassis. ## Chassis Maintenance ### Lens Cleaning Utilize a UAV landing pad to reduce the amount of dust and debris the camera lenses are exposed to. If the lens still happens to get dirty, use professional lens cleaning wipes to clean the camera lenses on. Wait 10 minutes after cleaning and check to make sure the lenses look clear, dry, and no residue remains. ### Tightening Screws Onboard screws for both the payload and mounting mechanism should be checked for tightness every 10 flight hours. ## System Calibration ### Geometric/Boresight Calibration GRYFN recommends that each Gobi system have a new boresight calibration completed every 12-24 months. ### Radiometric Calibration Headwall recommends that the Nano HP has a new radiometric calibration completed every 12-24 months. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
