China to have GPS covering Asia by 2010?

China’s satellite navigation officials intend to have an operational GPS system covering all of Asia by 2010. However, the officials are giving few details on the deployment plans for their GPS system. China is yet to complete the frequency coordination with the United States, Europe, Russia and others despite the fact that it is a member of the International Committee on Global Navigation Satellite Systems (ICGNSS) which was founded to ensure global interoperability of navigation satellite networks.

According to Space.com, Chinese officials said at the Toulouse Space Show that China’s global Compass/Beidou system would be fully compatible with the U.S. GPS, European Galileo, and Russian Glonass global navigation constellations.

Japanese officials have expressed concerns about the Chinese plans because Japan is developing its own regional system called the Quazi Zenith Satellite Systems which will have three satellites in orbit with an apogee over Japan and Asia. When the U.S., Russian, Chinese and European medium Earth satellites are added together there could be 120 operational navigation satellites in medium Earth orbit.

The Chinese satellite system will include an encrypted channel, presumably for use by the Chinese military.


While Microsoft Vista is struggling to get the public’s perception, Bill Gates said that 140 million copies of Microsoft Vista have been sold. However, Bill Gates did not clarify whether those were licenses or retail copies. Microsoft first made such an announcement when they crossed the 100 million mark of Vista sold at the end of last year.

Virtual Console USB Duplicator

Imagine a device that can copy the contents of a USB drive to 60 other USB drives at a time. Virtual Console USB Duplicator can do that, it is designed for duplicating the content of a USB drive to 60 others at a time, thereby saving time and energy.

I have been searching the web for an asterisk behind NAT configuration but couldn’t find a short but definite example so I decided to create a working example configuration of asterisk behind NAT. So if you guys are currently having problems configuring your asterisk behind NAT, please feel free to use my example below:

 

Put the following in your rc.local:
iptables -F
iptables -t nat -F
iptables -t mangle -F
iptables -t nat -A POSTROUTING -o eth0 -j SNAT –to your.public.ip.here
echo 1 > /proc/sys/net/ipv4/ip_forward
iptables -t nat -A PREROUTING -p udp –dport 10000:20000 -j DNAT –to-destination 192.168.30.1
iptables -t nat -A PREROUTING -p udp –dport 5060 -j DNAT –to-destination 192.168.30.1
iptables -A FORWARD -p udp -s 192.168.30.1 -j ACCEPT
iptables -A FORWARD -p udp –dport 10000:20000 -d 192.168.30.1 -j ACCEPT
iptables -A FORWARD -p udp –dport 5060 -d 192.168.30.1 -j ACCEPT

your sip.conf should be:
[general]
context=default
port = 5060
bindaddr = 0.0.0.0
context = default
externip = your.public.ip.here
nat=yes
localnet=192.168.30.0/255.255.255.0
canreinvite=no

Sample gateway-to-gateway SIP config for sip.conf:
[toyoursipprovider]
type=friend
host= sip.provider.gateway.ip
canreinvite=no
disallow=all
allow=g729
allow=ulaw
dtmfmode=rfc2833

ENJOY!
