AbstractMany processes in space are related to Poisson flows of particles. Usually, the aim of experiment is to study the intensity of such a flow. Each of the samples obtained in the course of measurement represents the number of particles detected during a sampling period and sample values are related with the flow intensity only statistically. So the less the sample value is, the greater the r.m.s. error in estimating the flow intensity. With any fixed "accumulation time" values of some samples are too small to provide required accuracy. Hence, these are redundant from the view-point of telemetering them to the Earth. A simple method is suggested for reducting this redundancy which assures a preset r.m.s. accuracy of measurement. The main feature of the method is that the accumulation lasts until the number of registrated particles reaches a preset level. In this case the "accumulation time" is variable and thus data compression is completely accomplished by appropriately organized aquisition.
