Qualcomm GSP 1620 Globalstar Satellite Packet Data Modem Product Specification Packet Modem Spec Rev6.
1. Globalstar Overview Globalstar is a voice and data telecommunications system utilizing a constellation of 48 Low Earth Orbiting (LEO) satellites, providing near world wide coverage (70N to 70S latitudes).
1.1.1 Space Segment The Space Segment is comprised of 48 LEO Satellites (and 8 additional in orbit spares) built by Loral Space Systems and operated by Globalstar LP in San Jose, CA. The advantages of a LEO satellite over MEO / GEO’s is the minimal delay, multi satellite handoff, extremely small antenna, lower power consumption, very small delay (~250 ms or comparable to terrestrial digital cellular), and the cheaper cost to the user. 1.1.
1.1.3 Coverage 1.1.4 Carriers Each coverage territory, typically aligned with country boundaries, has one or more Service Providers, which provide the user service, similar to a “cellular” model. The Service Provider or Carrier is licensed by Globalstar to offer service in a part of the world wide coverage area (one or more countries).
1.1.5 Distributors and OEMs: For the regular Globalstar Tri Mode Phone, cellular and satellite distributorships provide customers retail sales conduits to purchase, provision, and repair Tri Mode Phones throughout the world. For the GSP 1620 Packet Data Modem OEM’s and VARs directly integrate the module into a market specific product which is then resold to a business / industrial customer.

The Packet Data Modem operates in the “Globalstar (or satellite) packet data mode only”, as opposed to the Tri Mode Phone Product which has the additional Terrestrial Cellular (Analog and Digital) and Voice Capabilities. The module is powered by an external voltage source provided by the user and is intended for use in Supervisory Control and Data Acquisition (SCADA), remote telemetry / monitoring, asset tracking and monitoring and other vertical market applications.

Typical Applications Satellite Module ODU Tx GS Gateway Rx Router DCE DTE Ethernet Globalstar Module SCADA Terminal Data Port Internet Serial Connection Control Port Server SW A typical use of the GSP 1620 is depicted above showing a SCADA application. As shown the GSP 1620 can be thought of as a 9.6Kbps Full Duplex Satellite Modem. The modem uses typical Hayes AT commands (see Chapter 4). Standard RS232 interfaces facilitate ease of use and OEM / VAR application integration.

bi-directional data comunication solutions applications in remote locations for fixed or mobile use. With the GSP 1620 Satellite Packet Data Modem, you can cost-effectively retrieve data automatically from remote power substations, telecommunication concentration nodes, oil and gas wells, pipes, and offshore facilities. Unmanned sensors connected to the GSP 1620 Satellite Packet Data Modem can monitor remote operations and initiate alert notifications.
3.1.2 Oil and Gas, Pipelines • Monitor pipeline Cathodic Protection rectifiers to ensure operability. • Remotely test the pipeline electrical discharges and be alerted to electrical current buildup without having an inspector driving from one 40-mile checkpoint to another, manually checking each location. • Reduce costs, maximize use of personnel for repairs and maintenance, and receive real-time notification of a problem before a line ruptures. • Monitor production well heads.
• Send back images taken by a remote camera of the river or spillway conditions to help provide visual input along with the flow rate data. • Set up automatic control systems on pumping stations, water towers, storage tanks and lift stations. • Keep operations going smoothly in chemical tank monitoring. Don't pay for unnecessary inventory chemicals. • Monitor tanks above and below ground for process variables such as pressure, temperature, and pH. 3.1.
3.1.7 Banking and Retail Transactions • Set up banking ATMs in remote areas with reliable and cost effective Globalstar communications, without dependency on unreliable or expensive terrestrial communication lines. • Transmit credit card verification and remote retail authorization transactions. • Monitor performance and inventory of vending machines. • Provide redundancy for unreliable terrestrial or cellular communication systems. 3.1.
4. GSP 1620 Features: 4.1 Globalstar Satellite Service: The GSP 1620 offers Full Duplex (FDX) transmit and receive capabilities, at 9.6 Kbps, via the Globalstar satellite constellation, and utilizes Qualcomm’s CDMA Digital technology, for signal clarity and reliability. The Globalstar Air Interface (GAI) is based on a modified (proprietary) IS-95A standard adapted for Mobile Satellite System (MSS) operations. • Forward Link (Module Receive): 2484.39 to 2499.
session. The module has been operability tested with the following standard operating systems: • Windows 95/98/2000 • Windows NT • Mac OS • Palm OS • Unix / LINUX 4.2.3.2 Dormant Mode Service : The Globalstar system has the ability to keep the IP session “up” at the application layer (host and terminal end) while dropping the air link / traffic channel, to conserve Globalstar resources, and to decrease billing time to the end user.
having the system automatically assign a new dynamic IP address. Only Mobile Originated Calls may be made with Dynamic IP addresses. 4.2.3.5 Fixed IP Addressing Fixed IP addresses may be assigned “instead” of dynamic IP addresses. With a “fixed” IP address assigned the GSP 1620 can make Mobile Originated and receive incoming or Mobile Terminated Calls. Private IP addresses are “decoded” from the Module’s IMSI (International Mobile Subcriber Identity) so that precludes ROAMING between Gateways.

returning the last stored position. If you select the current position and you are NOT in a call, the module will return “ERROR”. If you select the stored position and there IS no stored position (you haven't done a position request EVER), you'll get an error. 4.7 Roaming: The module is capable of “fixed” operation in one location (building, tank, pipeline, and well monitoring and control) or “Roaming” type applications such as (trucks, rail cars, aircraft, shipping containers etc.).
5. AT Commands The AT Commands recognized in the Tri Mode Portable Phone Software Release R5.1 are listed below in Table (1) as well as those specifically developed for the Packet Data Module Table (3): Commands that are recognized, but not supported on the module (such as the speaker volumes) are listed in Table (2).

6. Hardware Description 6.1 Module Mechanical Description The Globalstar GSP 1620 Globalstar Satellite Packet Data Modem is a sandwich made of two circuit card assemblies (CCAs) which are open and unprotected. As a result, the GSP1620 must be shielded from direct impacts, precipitation, and particulates. I/O is obtained through four connectors. Power, data, and control functions are accessed via a 25 pin “D” style connector.

This mode of operation is useful in cases where power to the module as well as the rest of the system might be turned off periodically to conserve battery power. In case the module “hangs up” and the watchdog circuit doesn’t reset the module, the user has the option of resetting the module by pulling the MODULE_RESET_N low. Pulling the line low has the effect of a power on reset and not just a watchdog reset. 6.3.2.
• The baud rate is user configurable from between 300 and 115.2Kbps. The baud rate is adjustable in software. • In case of a reboot (due to fatal errors or any other reason), the DCD line will be set inactive so that the user application can detect a reset condition and take the necessary action. • Functionally the Data Port integrates AT Commands and Alert Messages as well as Application Packet Data PPP traffic. • The Data Port provides limited deconfliction of PPP vs.
