GeoStar UAV FAQs


 IS IT APPROVED BY THE FAA?
 YES!  Beginning on August 25th, 2014, AeroLogix and the GeoStar UAV system were approved for public (government) flight operations with Le Sueur County, Minnesota under FAA Certificate of Exemption and Authorization (COA) 2014-CSA-35.  Flight operations commenced immediately and are authorized under 2014-CSA-35 until August 2016.


 Since April, 2015, AeroLogix has been approved by the FAA to conduct commercial UAV operations with GeoStar UAVs under Section 333 of the 2012 FAA Modernization and Reform Act.  Our “333 exemption” allows AeroLogix to operate GeoStar UAVs commercially to private and public customers immediately. 


 HOW MUCH OF THE AIRFRAME DOES AEROLOGIX MANUFACTURE?
 A GeoStar UAV begins life as a high-quality composite 4-meter model sailplane.  The basic airframe components of
the wings, fuselage and tail are pre-built.  AeroLogix then modifies the airframe and installs all the necessary equipment to make it a fully functional Unmanned Aerial Vehicle.  These installations include:

 -Electric Propulsion System
 -GPS/INS Autopilot Navigation System

 -Flight Control Servos
 -Real-time Telemetry Link
 -Parachute Recovery System
 -Internal Digital Imaging System
 -HD Video Camera
 -Power Conditioning Systems
 -Wire/Connector Harnesses
 -Carbon Fiber Landing Gear/Steerable Tailwheel
 -Paint/Graphics


  4 METER (13.3ft) WINGSPAN?  WHY SO BIG? 
  AeroLogix designed and built the GeoStar UAV when no suitable commercially available UAVs could be found.  Designing and building our own UAV
allows AeroLogix to optimize the systems and flight characteristics for precision Aerial Photography.  The size was generally driven by selecting an airframe with "room to grow" in terms of weight and wing loading.  The following factors were also considered: 

 -Slower operational airspeeds

 -Stable flight characteristics 

 -Relatively large camera/optics for a UAV
 -Internal mounting of all components
 -Layout flexibility for camera, parachute, batteries
 -Easily seen
 -Endurance 


 WHY A PARACHUTE?

 AeroLogix installed a parachute as a standard recovery system when operations dictate confined recovery locations.  It also serves as an important safety feature that can safely recover the GeoStar in the event of an emergency.  The parachute is large enough to recover the GeoStar safely and without damage.

 WHY NOT A "COPTER" STYLE DRONE? (QUAD/HEX/OCTO COPTERS)
 With any aircraft there is always a compromise between power, size, speed, payload and endurance.  We could not find a commercially available airframe,
fixed wing or rotary wing, that could meet the payload and performance specs we desired at a reasonable cost.  As a result, we designed and built our own -  The GeoStar UAV.  Additionally, we (correctly) predicted that the FAA would require "Small UAVs" to operate within visual range.  The copters are much smaller and much more difficult to keep in visual contact when flying at the higher altitudes required for most aerial surveys.  The size, shape and color of the GeoStar UAV facilitates visual contact. 

 HOW FAST DOES IT FLY?

 Top speed = 65mph. 

 Landing speed = 25mph.

 Collecting photos = 40-45mph

 HOW HIGH DOES IT FLY?

 We typically collect from 500-600 feet above the ground for our Public-Sector GeoStar operations with Le Sueur County, MN.  Commercial operations under our "333 Exemption" are currently authorized up to 400 feet AGL.  AeroLogix is seeking FAA authorization for 333 operations up to 600 feet. 

 WHAT DOES IT USE FOR IMAGING? 

 The GeoStar incorporates a 36 megapixel digital imager.  Sensor size is equal to 35mm film (“full frame” sensor).  We use fixed-focal length lenses of 24, 28, 35 or 50mm to achieve various Ground Sample Distances (GSD).  A small HD video camera is also installed to capture ground video.


 ARE HYPERSPECTRAL OR LIDAR SENSORS AVAILABLE?

 Not at this time.  We are talking to a vendor with a LIDAR sensor and exploring options for VNIR/MWIR sensors.  If sufficient demand is present, we will pursue these sensors.  We can say the GeoStar is capable of carrying these sensors based on weights, power requirements and form-factors.


 HOW AUTOMATED IS IT?

 The GeoStar can be programmed for a fully automated takeoff.  One switch activates a series of autopilot functions that advance the throttle, steer it down the runway surface, rotate and climb out to a desired altitude.  Once safely airborne the autopilot steers the GeoStar along precision flight paths optimized for aerial survey.  It also returns to the launch point and orbits via the autopilot until the human pilot takes over and either deploys the parachute or lands it on the wheels.

 WHAT DOES IT USE TO NAVIGATE?
 The GeoStar UAV uses an internal GPS and Inertial Navigation System.  It also uses a barometric altimeter, pitot-static airspeed sensor and magnetic compass.  The mission is
preplanned and loaded into the autopilot before launch.
