Polhemus Viper
Polhemus Viper is a series of electromagnetic tracking systems from Polhemus. The Viper line includes the Viper 4, Viper 8, and Viper 16. The Viper 4 and Viper 8 are both in the same physical enclosure. The Viper 16 is twice as tall as the Viper 4 or 8.
The Viper series is the top in Polhemus' line of products.
Final assembly is done in the United States.
Viper sensors attach to the SEU using a connector that is the same physical shape as USB-C, but it has different electrical connections.
It is compatible with the Micro Sensor from Polhemus.
Viper units can be configured to use electromagnetic eddy current distortion correction, termed by Polhemus as Fly True Technology (FTT).
Specifications[edit]
- Update rate: Viper 4 is 240hz per sensor. Viper 8 and 16 are 960 hz per sensor.
- Connections: USB and/or RS-422
- Latency: About 1 millisecond at 960hz, about 2 milliseconds at 480hz, and about 3 milliseconds at 240hz.[1]
- The accuracy within a 30 inch radius from TX2 source, when staying perfectly still: 0.015 inches root mean square (RMS) for position, 0.10 degrees RMS orientation.[1]
Software[edit]
The Viper SEUs interface with software based on the Viper Native Command Protocol (VNCP).[2]
Construction[edit]
Viper SEUs use a 5 volt, 8 amp power supply.
