What is IGate ham radio?
Around the world, amateurs operate internet gateway (IGate) systems to route received packets from the packet radio-based network to the internet-based APRS-IS service and back; these gateways can be receive-only or also have transmit capabilities.
What is a IGate?
An IGate (Internet Gateway) has two functions: to pass all packets heard on RF to APRS-IS and to pass all message packets destined for local stations to RF (if a bidirectional IGate). The first part of this is sometimes misunderstood. Generic queries are APRS query packets that are not directed to a single station.
What is the APRS frequency?
144.390MHz
Because APRS uses a single shared frequency (in North America it’s 144.390MHz), everyone can see what everyone else is doing. By keeping the packets short and turning off transmitters between sends, many people can share the same frequency.
What is an APRS digipeater?
“Digipeater” is short for “Digital Repeater”; a repeater for packet data rather than voice. Unlike the standard voice repeater that receives on one frequency and retransmits what it hears simultaneously on another frequency, the usual digipeater is a single frequency device.
Is iGate and Capgemini same?
Capgemini is acquiring iGate for $4 billion, which makes it the largest merger and acquisition of any IT company founded by Indians. Globally, this will be the largest acquisition of any IT Services based company.
When did Capgemini take over iGate?
Its revenues in 2014 were over US$1.2 billion, and it has a workforce of over 31,000. The firm had over 70 offices and customer delivery centers in North America, Europe, Asia and Australia. On April 27, 2015 French IT services group Capgemini unveiled a deal to acquire IGATE for $4 billion.
Is APRS digital?
Automatic Packet Reporting System (APRS) is an amateur radio-based system for real time digital communications of information of immediate value in the local area. Data can include object Global Positioning System (GPS) coordinates, weather station telemetry, text messages, announcements, queries, and other telemetry.
Can I build an APRS Internet gateway with a Raspberry Pi?
Recently amateur radio hobbyist WB20SZ wrote in to us to let us know about his work with creating an easy to build receive only APRS internet gateway (IGate) with a Raspberry Pi and RTL-SDR dongle. The process involves using WB20SZ’s “Dire Wolf” software which is a free Linux based APRS encoder/decoder.
Can a Raspberry Pi be used as a receive-only iGATE?
This article describes how to configure a Raspberry Pi 2 or 3 and a terminal node controller (TNC) as a receive-only IGate to relay radio traffic to the APRS-IS service, where it can be accessed by amateurs around the world. There are no licensing requirements for receiving amateur radio traffic, only for transmitting.
Can the Raspberry Pi be used as an APRS TNC?
The main addition required to the Raspberry Pi to turn it into a fully-fledged APRS TNC is a radio interface. As it turns out, there’s a commercially available HAT for the Rapberry Pi designed for just this purpose: North West Radio UDRC II.
What is an APRS-is gateway?
A Raspberry Pi-based APRS-IS gateway Around the world, amateurs operate internet gateway (IGate) systems to route received packets from the packet radio-based network to the internet-based APRS-IS service and back; these gateways can be receive-only or also have transmit capabilities.
