product review processing option in gps pathfinder office software. using data from fixed reference stations around the world, the data collected in the field is post-processed. earlier tests with the geoxt handhelds performed by this magazine indicated that the results of code post-processing are similar to those with sbas collection. comment from trimble trimble mapping & gis division thanks geoinformatics for conducting this product review and for providing the opportunity to comment on their findings. as mr. lekkerkerk points out, the juno sc well suited for mobile workers engaged in data collection and attribute update who require connectivity in the field. to support these types of users, terrasync does manage information from the internal camera, including gps location, when a data dictionary is created that contains a picture attribute. furthermore, the camera issues noted, including the long shutter lag as well as several image colour problems, are due to be resolved in an april update of windows mobile 6.1. conclusion the juno sc handheld is an affordable alternative to its bigger brothers, but do not expect miracles from it in the sense of accuracy. it is however a good alternative for attribute updating or object recovery, especially when using terrasync software. one thing that disappoints me is the camera since it is very hard to use due to the shutter lag. the method chosen by trimble for transferring data files helps to keep the paths in the data to the photograph correct whenever pathfinder office is used for data processing. huibert-jan lekkerkerk hlekkerkerk@geoinformatics.com is freelance writer as well as project manager at idsw. this review was done in cooperation with the students from the fifth skilltrade course hydrography b in rotterdam.this article represents their personal views. for more information on the gps: www.trimble.com. differential positioning the juno sc handheld has a built-in sbas receiver, allowing it to receive corrections from the available waas and egnos satellites. the downside to using sbas is that the satellites visible in europe (egnos) are relatively low on the horizon resulting in potential obstruction of the differential signal in build-up area s or under tree canopies. trimble however offers a post- we turn game plans into goals. winning solutions from inpho. see the world with different eyes. to play in the premier league of photogrammetry, you need just the right system provider. that partner is inpho, well-known for its first-class systems of exceptional performance level. our high-quality software and our devoted customer support ensure that your team is outstandingly positioned to hit the mark so that your projects culminate with the winning scores. geo-referencing geo-capturing geo-modelling geo-imaging www.inpho.de 061_az_geoinformatics_185x134_4c1 1 latest news? visit www.geoinformatics.com 20.10.2008 12:14:53 uhr 9 april/may 2009
