Topographic surveys |
|
As-built surveys |
|
Road design |
|
High-accuracy static surveys |
|
Control surveys |
Flexible and Dependable
Radian can be used for real-time kinematic (RTK) surveys to achieve
centimeter level accuracy and also in post-processed surveys to achieve
millimeter level accuracy.
Radian offers a 12-channel, dual-frequency
(L1/L2) GPS receiver that features a removable PCMCIA memory card,
communications port power output, front panel operation and LED status
indicators.
Every Radian receiver is delivered in a

|
A
single frequency model, for entry-level or occasional users, who need to
perform static baseline surveys, yet want the flexibility to upgrade in
the future. |
|
A
dual-frequency model for post-processed surveys, where speed is
critical. |
|
A
dual-frequency model capable of Real-Time Kinematic and static surveys,
where flexibility is required, and a wide variety of jobs are
encountered. |

satellite geometry, baseline length, occupation time, number of SVs
tracked and multipath effects.
