2.3 Length of baseline
The accuracy of satellite signal received with GPS receiver can reach millimeter level, but
due to the signal suffers ionosphere and troposphere infection when transmitting through
aerosphere, the accuracy will be depressed |

survey, we usually use annexed traverse as special example according to practical situation and the
net usage. This requirement for this traverse is the high accuracy for the known vectors between
two point ends. Furthermore, the amount of annexed traverses cannot exceed the limits. |

The net design mainly subject to the users' requirement, but outlay, time interval of
observation, type of receiver and the receiver amount, etc also relate to the net design.
In order to satisfy the users' requirement, we should keep the principle as follows |
