Details

Pacific Crest PDL Data Link
The PDL is an advanced, high speed, wireless data link that is designed specifically for GPS/RTK applications.

Features:

  • Fast Over-the-Air Data Rate
    • 19,200 bits per second
    • Reduced latency provides better GPS position information
    • Lower power consumption allows longer field operation
    • Greater throughput handles both GPS and GLONASS
  • Enhanced User Interface - Channel display and buttons
    • View and change radio channel
    • Monitor charge status and other parameters
  • Intelligent Protocols - Forward Error Correction (FEC), Aut oBase™ and AutoRover™ technology
    • FEC provides improved noise immunity and range
    • Base automatically selects channel with AutoBase
    • Rover automatically locks to base with AutoRover

    • Facilitates GPS equipment mix and match
    • Provides upgrade path for existing installations


Specifications:

General
Serial Port Interface RS-232 compatible. 1200 to 38400 baud operation with 1 start, 8 data, optional parity, and one stop bit.
Power Supply 9-16 VDC. PDL Rover quiescent/receive power consumption 0.3W. PDL High Power Base quiescent/receive power consumption is 1.9W. PDL High Power Base in the low/high RF power setting consumes 13W/125W during transmission. The PDL Low Power Base quiescent/receive power consumption is 0.9W. The PDL Low Power Base when transmitting consumes 5W/11W. (PDL Base power consumption measured at 12.5 VDC.)
Radio
Frequency Ranges Contact factory for available frequency ranges. Synthesized frequency control with approximately 1600 channel capability. Channel spacing 25/12.5 kHz. 2.5 ppm frequency reference.
Transmitter Carrier power 2-Watts or 35-Watts nominal for the High Power Base. Carrier power for the Low Power Base is factory programmable for the 0.5W or 2W. Output impedance 50-ohms. Modulation distortion is less than 5%. Transmitter attack time < 18 ms. Spurious and harmonic FM -55 dBc. FM hum and noise -40 dBm.
Receiver Sensitivity -116 dBm or better (12dB SINAD). Selectivity for the PDL HPB and Rover is >-60 dB. Selectivity for the PDL LPB is >-70dB. (9600, GMSK, 25 KHz), and >-60 dB (19,200, 4LFSK, 25 KHz). FM hum and noise -40 dB. Conducted spurious -65 dB. Carrier detect attack time 2 ms.
Modem
Transmission Rate 19,200 or 9,600 bits per second (Four-level FSK) 9,600 or 4,800 bits per second (GMSK)
Transmission Protocols Transparent, packet switched, auto-repeater, fast asynchronous, Trimtalk™.
Forward Error Correction and Detection With FEC enabled, data is encoded by a block code. The data is interleaved in blocks of 20 words, giving burst error correction capabilities for up to 20 consecutive corrupted bits. 16-bit CRCs are generated and sent with every block of data providing 100% error detection for burst errors shorter than 16 bits, and 99.9984% detection of all other burst errors.
Modulation Gaussian Minimum Shift Keying (GMSK) with BT of 0.5 (4800, 9600 bps link rate). Four-level FSK (9600, 19200 bps link rate).
