the MEDUSA gamma ray logging system  Our services are organized around two different scenarios: 1: Sale of our complete system to the client: In this case our client purchases the complete system, including all the peripheral equipment and software. In most cases the client chooses to use our services for training and after-sales services, such as quality control, data backup, environmental corrections, gridding and data interpretation as well as integration with other remote sensing data. 2: The client contracts us to perform an airborne survey In this scenario the client provides the plane and pilot, and we do the rest. This scenario can offer significant cost and efficiency benefits for the client compared to the services provided by the classical airborne survey contractors. The reason for this is that our system is very light, and can be mounted on any single engine small aircraft. This means that we can make use of local aircraft and pilots, which often offers considerable cost savings. Pilots that have experience with the local terrain and weather conditions will be able to optimize the efficiency of the flights.
