The Venus368lp has still one features that are is matched by any other low cost chip: the 20Hz update rate. It is a good reason to keep it here in our hall-of-fame.
There are a lot of things special about this receiver:
- the top sensitivity (-165dBm),
- the power consumption (50mA @3.3V MAX),
- the size (1cm2 with TCXO, antenna bias sensor, and flash),
- the internal flash ram to store up to 75k positions,
- the automatic support for an external flash for data logging
- 20Hz positioning rate
We really would like to know what is 20Hz rate for! Supposedly, someone might want to track a rocket
, or a bird
in free fall to catch its prey, or a pretty fast car
for immersive reality games. It's all about the limitations in terms of acceleration then?
