Pose estimation / Localization in GPS denied environments ?

I use GPS to estimate where my robot is in the global frame. However, in certain areas GPS signals are lost. I was wondering what the standard techniques are for outdoor robots to find the pose of the robot when there is no GPS.

I have been looking into SLAM techniques with a Hokuyo laser. Wanted to know if there are standard preferred methods in the robotics? Radar? Stereo Cameras?

Thank you.

You might want to specify the environments for SLAM. When you are operating near the max range of the sensor SLAM won't work well. The good thing is that bad GPS is often caused by close-by buildings.

The environment is similar to what you mentioned. The laser mostly gets a lot of hits and stuff is not outside the range. It works okay with amcl and laser I'm using. My question is more to find out what are the best techniques used in these conditions?
