The GPS antenna cable that ships with every 3DM-GX3-35 and 3DM-GX3-45 is 3 meters in length.
Cable length is important. The longer the cable, the lower the signal strength. If the user lengthens the cable, the signal strength will diminish. The loss of signal strength can only be empirically determined by trying out a particular installation. Loss of signal strength will manifest itself in the number of satellites seen, quality of data reception from satellites, etc.
No. The GPS Receiver only receives standard GPS signals. It does not receive Differential GPS (DGPS) signals. If the user requires DGPS input, the GX3 will accept DGPS via an external feed and in the case of the 3DM-GX3-45, incorporate it in its Kalman filter processing. To be clear: the on-board GPS will be bypassed in favor of the external GPS.

Each device has its own billing plan. This allows the user to upgrade critical devices to prevent service disruption, and select the plan most appropriate for each device's usage pattern. Each upgraded device will have its own base charge, and accumulate additional usage charges based on its plan.
When devices on the basic plan reach their maximum MDP, SensorCloud will reject any further data uploads. Similarly, API calls will be rejected after the allotment is exhausted. All previously uploaded data remains accessible through fastgraph. For upgraded devices, SensorCloud will not reject any requests, but will accumulate additional usage costs. These additional costs are defined in each of the billing plans. Additional costs will appear at the end of the month when the billing cycle is renewed.
Each SensorCloud billing plan operates on a monthly cycle. The month begins when the user enters their billing info. A user can upgrade and downgrade devices at any time in the month. Upgrades made during a billing cycle will be pro-rated for the remaining days in the billing cycle. At the end of the billing cycle, all upgraded devices are automatically renewed and MDP and OpenData API allotments are refreshed.
No, the on-board GPS does not support this.... but if the user has a GPS that does, this external GPS can input its 'RTK-groomed' measurements into the 3DM-GX3-45 and the 3DM-GX3-45 will incorporate those measurements into the Kalman filter. To be clear: the on-board GPS will be bypassed in favor of the external GPS.
Wikipedia's definition: http://en.wikipedia.org/wiki/Real_Time_Kinematic
Real Time Kinematic (RTK) satellite navigation is a technique used to enhance the precision of position data derived from satellite-based positioning systems, being usable in conjunction with GPS, GLONASS and/or Galileo. It uses measurements of the phase of the signal′s carrier wave, rather than the information content of the signal, and relies on a single reference station to provide real-time corrections, providing up to centimetre-level accuracy. With reference to GPS in particular, the system is commonly referred to as Carrier-Phase Enhancement, or CPGPS. It has application in land survey and in hydrographic survey.
Yes. Node Commander has a function that allows the user to drag and drop its CSV data files into SensorCloud.
Yes, absolutely. SensorCloud is viewable on Android and IOS devices.
SensorCloud has a very powerful function called MathEngine. MathEngine allows users to process vast quantities of sensor data in the cloud, and on the fly. Users can either create simple custom scripts for basic operations such as averaging and filtering, or, they can implement advanced data processing algorithms for generating condition indicator metrics such as metal fatigue or bearing failure.
