Surveying Products:E650

1. Can E650 acts as reference station and transmit the correction data via GSM phone and radio modem at the same time?
   No. But both models can standby at the same time, and can be switched freely.
2. Can Li-Ion battery be removed to charge with the external charger?
   Li-Ion battery can’t be removed because of the ‘all in one’ design in order to ensure the tightness packaging. But generally there is no need to charge out, because the battery can be used continuously for 12 hours or more.
3. Can we add some background map such as the construction design or aerial photo map to the E650 system for staking out and data updating?
   Not available.
4. Can we define the code and feature of the measured feature? If yes, is there any limitation on the number of code and attribute?
   Code can be imported, but defined feature is not available. The imported code length should less than 32 characters.
5. Can we customize the coordinate system such as the map projection and datum transformation parameter?
   Yes.
6. Can the compact flash data storage be removed from the receiver for data download?
   The compact flash data storage couldn’t be removed from the receiver because of the ‘all in one’ design. And for the RTK measurement, we don’t need to remove the storage because data is stored in the controller and we just need to download data from the controller.
7. Do you have an option of receiving GLONASS signal?
   Not available.
8. Is it necessary to connect the RF Amplification System for the two receivers to communicate during RTK or only for very long distance?
   It's not necessary to connect RF amplification system in a small area about 3 to 5 kilometers. If the RTK distance is much longer, we'd better connect the RF amplification to achieve better effect.
9. The receiver can’t receive satellite signal normally.
   Please check:
   Whether have just initialize the receive board;
   Whether there is interferential source nearby.
