Part 3. Design of a new robot for generic(universal) use of mobile photometer for low,moderateandhighspeedmobility.

Whatpreviousresultsshow?-  Amodified CE318T photometer can be considered for some applicaCons like satellite

-  MoreaccuratenavigaConsystem(IMU)mustbeintegrated(shipheading)

-  Exactviewinggeometrymustberecordedforaerosolinversionprocess.

-  DayCme and nighyme AOD and their combinaCon with ceilometer possible (AQABAcampaign).

-  Less expansive soluCon (systemexist and add-on component has beendeveloped andalmostfullyvalidated)has:
