article adl series pacific crest new product line pacific crest has launched a radio telemetry product line called the adl series. pacific crest s radios are used in the gnss industry where it is used for example to transmit rtk corrections. by our editorial staff improvements in the radio protocols used have made it possible to increase the maximum speed over the air to support 19k2 when selected a 25khz channel for both gmsk and 4lfsk modulation based protocols. this will support the ever increasing need for data telemetry bandwidth due to the constantly increasing availability of positioning satellites. the number of protocols have also been updated and increased to be compatible with all generally used standards. the new product line will still remain compatible with earlier pacific crest radio products. the adl vantage will become the successor of the current pdl lpb radio and the adl vantage pro will replace the pdl the new products all are based on a core module called the adl foundation. the adl foundation can be used as an oem module for manufacturers and system integrators and also forms the basis of the following products: adl vantage (display, up to 4w) adl vantage pro (display, up to 35w) adl sentry (no display, dual com port, up to 4w) historically pacific crest has a focus on the gnss industry but also service other markets. with the new product range more markets could be even better accessible, such as marine, scada, remote sensing and control of various systems. the adl foundation is fully programmable for output power between 0.1 and 1w. the radio comes in a 40mhz wide band which is good news for internationally operating companies who are not willing to keep stock of many different radios covering only a limited frequency band. with only two 40mhz wide radios the whole of the uhf band is covered from 390 430 mhz and 430 470 mhz. also the channel spacing is programmable between 12.5khz and 25khz. pacific crest's new advanced data link series. heart of the new adl products, the adl foundation. this product is also available for system integrators 68 september 2009
