GPS to monitor sex behavior of giant pandas
 Chinese and American scientists are using the GPS to monitor the sex behavior of giant pandas in deep mountains. The Chinese Academy of Sciences Institute of Zoology and the US Zoological Society of San Diego are joining hands in a three-year program in the Foping Natural Reserve, which costs 660,000 US dollars.
USTDA awards grant for GIS Project in Morocco
The implementation of a national GIS based information management system to improve Morocco’s exploration and production of oil, natural gas, hydrocarbon, and other minerals is the goal of a USTDA grant that was awarded this week to the ONHYM of Morocco.
Antarctica’s crevasses to be mapped
To ensure the safety of the 25th Indian expedition team which leaves for Antarctica later this year satellite imagery will be used to identify the dangerous crevasses there. Earlier expeditions used helicopters to identify them. For the first time the Indian team will use satellite-based imagery and GIS to monitor those crevasses.

Real Time Kinematic GPS in an Urban Canyon Environment
Adeniyi Iyiade
University of Plymouth,
Plymouth,UK
As GPS measurements like other survey measurements are not devoid of errors. In Real Time Kinematic (RTK) positioning in an urban canyon environments where the GPS signals are blocked by high buildings and there are not enough satellites signals in estimating the positions of the user, computation of the antenna positioning is a major problem. The research work uses an Extended Kalman Filter (EKF) as an attempt to reduce the effects of errors such as the atmospheric errors, multipath and receiver noise on GPS signals during transmission. However, some unmodelled biases still remain in the GPS observations, stochastic models were used as a quality indicator to identify and isolate such biases. The end result shows an improved coordinates solution.
Fuzzy Point Averaging of the GPS Position Components
M R Mosavi
Assistant Professor
Department of Electrical Engineering
Iran
GPS can be a powerful tool that assists researchers locates points of interest. While GPS provides an easy way to collect latitude and longitude, it is important to remember that there are errors inherent in any GPS collected point. In order to use GPS most effectively, users need to decide on a strategy for dealing with the errors.
The goal of this paper is to obtain better accuracy than simple point averaging from a low cost GPS receiver. The theoretical backgrounds for better accuracy are based on the principle of averaging and fuzzy logic schemes.
