What is the sampling period of the SL1?
There are two components to this answer. First, the SL1 has a “sample period” configurable via the USB interface that sets how often it locates the sun, reports the pointing error, and saves this value to the internal nonvolatile memory. This period can be set to a wide range of values (we find many customers use 30-60 seconds), but typically can not be set to any shorter than 5-15 seconds, depending on other sensor settings. This time limitation is due to various algorithms and stabilization routines performed on the sensor for each reading. However, the portion of this time spent acquiring of the sun position itself is much shorter, less than a second at the very beginning of the sampling period, so there is no need to worry about the sun moving significantly during the reading.
