Mitigating Residual Tropospheric Delay to Improve User’s Network-Based Positioning
Existing apriori tropospheric models are not sufficiently accurate to remove tropospheric delay from GPS observations. Remaining effects of residual tropospheric delay need to be estimated to ensure high accuracy and reliability of GPS positioning. Other researchers have shown that implementati...

| description | Existing apriori tropospheric models are not
sufficiently accurate to remove tropospheric delay from
GPS observations. Remaining effects of residual
tropospheric delay need to be estimated to ensure high
accuracy and reliability of GPS positioning. Other
researchers have shown that implementations of network-based positioning techniques can adequately model the
residual tropospheric delay as well as ionospheric delay
and orbit biases. However, the effectiveness in removing
residual tropospheric delay is highly dependent on the
degree to which the wet component from the troposphere
can be estimated or mitigated, an effect which shows
strong variation with time and space. The aim of this
paper is to illustrate the performance of an existing
apriori tropospheric model and to discuss some issues
concerning the estimation of the (total) tropospheric delay
in the equatorial area. Finally, the network approach is
applied to mitigate the effect of residual tropospheric
delay. Some preliminary results from test experiments
using GPS network data from an equatorial region, a
location with the highest effect of tropospheric delay, are
presented. |
